2x-5y = 10
Solve for X
ok first i add 5y on both sides
so i get
2x = 10 + 5y
then i divided 2x on both sides
so i get
x = 10 + 5y / 2x
but how am i supposed to divide 10/2x and 5y/2x when they’re different variables??
someone please explain.
Answer:
Hey there!
2x-5y=10
Add 5y on both sides to get: 2x=10+5y
Divide by 2, not 2x. This will isolate the x.
x=5+2.5y
x=2.5y+5
Hope this helps :)
Answer:
x = 5 + 5y/2
Step-by-step explanation:
When you get to 2x = 10 + 5y,
you should divide both sides with 2 only instead of 2x. Because if you divide 2x on both sides, the left side would only remain 1 (since 2x/2x = 1)
2x = 10 + 5y
x = (10 + 5y) / 2
x = 10/2 + 5y/2
x = 5 + 5y/2 .( or 5 + (5/2)y)

Three consecutive odd integers have a sum of 45. Find the integers.
Answer:
13, 15, 17
Step-by-step explanation:
Each digit must be odd, and to get consecutive odd integers, you must add using the multiple of 2:
Let the least number be "x". Set the equation:
(x) + (x + 2) + (x + 4) = 45
Isolate the variable, x. First, combine like terms:
(x + x + x) + (2 + 4) = 45
(3x) + 6 = 45
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 6 from both sides:
3x + 6 (-6) = 45 (-6)
3x = 45 - 6
3x = 39
Divide 3 from both sides:
(3x)/3 = (39)/3
x = 39/3
x = 13
Your first number (x) is 13. Solve for the other 2 numbers:
(x) = 13
(x + 2) = 13 + 2 = 15
(x + 4) = 13 + 4 = 17
13, 15, 17 are your numbers:
Check:
13 + 15 + 17 = (13 + 15) + 17 = 28 + 17 = 45

An auto weighing 2,500 pounds is on a street inclined at 10 with the horizontal. Find the force necessary to prevent the car from rolling down the hill.
Answer:
1931.7N
Step-by-step explanation:
We are told in the question that :
An auto ( a car) weighs = 2500 pounds
It s inclined at n horizontal Ange of 10°
We are asked to find the force that would prevents it from rolling down the street.
Since the unit for Force = Newton or kgm/s²
Step 1
Convert Weight in pounds to kg
1 pound = 0.453592kg
2500 pounds =
2500 pounds × 0.453592kg
= 1133.981kg
Step 2
Find the force that would prevents it from rolling down the street.
Force = Mass × Acceleration due to gravity × sin θ
Acceleration due to gravity = 9.81m/s
Force = 1133.981kg × 9.81 × sin 10°
Force = 1931.7237321 N
Approximately = 1931.7N
Which degrees is the answer
Answer:
75°
Step-by-step explanation:
Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°
All we need to do is simply subtract 15° from 90° to find m∠ATB:
90 - 15 = 75°
Answer:
75°Solution,
Let m<ATB be X
[tex]x + 15 + 90 = 180[/tex]
(sum of angle in straight line)
[tex]x + 105 = 180[/tex]
subtract 105 on both sides
[tex]x + 105 - 105 = 180 - 105 \\ x = 180 - 105 \\ x = 75[/tex]

An experiment is to be conducted using environmentally safe peppermint oil to study the effectiveness of deterring mice from infesting dwellings. In one
dwelling, the peppermint oil will be dispersed via essential oil diffuser; in the other dwelling it will be placed on areas where mice could enter the dwelling. The
researchers will determine the adverse reactions of the mice to the peppermint oil by counting the number of mice in each dwelling after one week. There are
20 mice available for the experiment, and the researchers will use 10 mice for each dwelling. For this experiment, identify the treatments, experimental unit, and response variable.
Treatments: how the peppermint oil is dispersed
Experimental unit: number of mice in the dwellings
Response variable: mice
Treatments: number of mice in the dwellings
Experimental unit: mice
Response variable: how the peppermint oil is dispersed
Treatments: mice
Experimental unit: how the peppermint oil is dispersed
Response variable: number of mice in the dwellings
Treatments: mice
Experimental unit: number of mice in the dwellings
Response variable: how the peppermint oil is dispersed
Treatments: how the peppermint oil is dispersed
Experimental unit: mice
Response variable: number of mice in the dwellings
Answer:
Option E is correct.
- Treatments: how the peppermint oil is dispersed
- Experimental unit: mice
- Response variable: number of mice in the dwellings
Step-by-step explanation:
The treatments in this type of statistical experiment refers to the part of the experiment that is tweaked, controlled or varied in the cases being studied. In this experiment, the method of essential oil dispersal is what is varied in the two experimental cases of this study.
Experimental Unit refers to the subject matters, who are participants in the experiment. They are the ones that the effect of the treatments is tested upon.
For this study, the experimental units are the mice subjected to either of the two methods of peppermint oil dispersal.
The response variable is how the experimental units (participants) respond to the treatments (experimental tweaks). Or how the tweaks manifest observable results in the participants of the study. For this study, the effect of the tweaks in the mice is shown in the number of mice that remain in each dwelling (where the two methods of peppermint oil dispersal have been implemented). Hence, the response variable is the number of mice in each dwelling.

Do hamsters preferred treats or blue treats? Two different supplements, which have no effect on taste, are used on identical treats to produce a red treat or a
blue treat. Volunteer hamsters are randomly assigned to either a red treat or a blue treat, and the researchers rate the treats based on how quickly the hamsters
eat them. Is blinding demonstrated in the experiment?
No, because the hamsters do not know the color treat they are getting
Yes, by having the experimenter in a separate room pick one of the two containers at random and having a treat pulled from that container remotely
No, because the hamsters know whether they are eating a red treat or a blue treat
Yes, by having the statistician analyzing the results not know which hamster sampled which treat
Yes, by having the hamsters eat the treats out of the container, so they don't know the color of the treat they are eating
Answer:
The answer is C.
Step-by-step explanation:
I took the test and got it right! Besides that, here's an explanation:
Blinding is when either the subjects (single-blind) or the subjects and researchers (double-blind) do not know what treatment they are recieving. In this case, the birds know what color treat they are getting, and the researchers do as well. Therefore, there is no blinding being done in this experiment.
If there was, the researchers and the birds wouldn't know the color of the treat, or ONLY the birds wouldn't know the color of the treat. Because this experiment is dependent on the color that the birds see, blinding would kind of contradict the whole point of the experiment.
As by, the blinding demonstrated in the experiment is not there, because the hamsters know whether they are eating a red treat or a blue treat.
What is research?As the research is defined as, in accordance with suitable epistemologies set by specific occupational group fields and academic discipline. As documentation of critical collection; and analysis and interpretation of that data/aggregation.
The birds know what color happening they are getting on, and the research worker do as well. Therefore, there is no blinding being done in this experiment. As binding is considered as, the subjects (single-blind) or the subjects and researchers (double-blind)
Therefore, The right option (C) is correct.

What is slope?The slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Given that, On February 2nd, Jordan is going on a class trip to Washington, D.C. He is saving his weekly allowance to use as spending money while on the trip. Each week, Jordan's parents give him the $8 he earned for the week,
The saving are
In 1st week = $86
In 2nd week = $94
Therefore, we can consider the coordinates as (1, 86) or (2, 94)
We know that, standard equation of a line = y = mx+c
Where, m is the slope,
We have here slope = 8
Finding for c, put x = 1 and y = 86
c = 78
Now finding the amount for 5 weeks, that means x = 5
y = 5x8+78
y = 118
Hence, The amount Jordan will have on 1st of the February is $118

DeShawn and Pranav each improved their yards by planting daylilies and shrubs. They bough
their supplies from the same store. DeShawn spent $143 on 9 daylilies and 4 shrubs. Pranav
spent $198 on 14 daylilies and 4 shrubs. Find the cost of one daylily and the cost of one shrub
Answer:
Daylilies cost $11 and shrubs cost $11
Step-by-step explanation:
Let's call the cost of daylilies as x and the cost of shrubs as y. We can write:
9x + 4y = 143 -- Equation 1
14x + 4y = 198 -- Equation 2
5x = 55 -- Subtract Equation 1 from Equation 2
x = 11 -- Divide by 5
9 * 11 + 4y = 143 -- Substitute x = 11 into Equation 1
4y = 44 -- Subtract 99
y = 11 -- Divide by 4

Start with the given:
Circle -3, square -6, and square 12.
Start with solving the circle that connects square -6 and square -12.
Since the two circles the surround the square are to be multiplied, divide the square value by one of the circle value.
In this case,
-6 ÷ -3 = 2
So now you have circle 2 and square 12. To solve the other square on the right, do the same technique done in the first part.
12 ÷ 2 = 6
Now multiply 6 and -3 to make the product in the square position.
6 × -3 = -18
So the answers:
Left Circle = 2
Right Circle = 6
Right Square = -18
Answer:
See below
Step-by-step explanation:
It would be like:
=> -3 * 2 = -6
=> 2 * 6 = 12

A professional basketball team made 37.9% of its three-point field goals in one season. If 80 three-point field goal attempts are randomly selected from the season, what is the probability that more than 35 were made? Use a TI-83, TI-83 plus, or TI-84 calculator to find the probability. Round your answer to four decimal places.
Answer:
The probability that more than 35 were made is 0.14686.
Step-by-step explanation:
We are given that a professional basketball team made 37.9% of its three-point field goals in one season.
80 three-point field goal attempts are randomly selected from the season.
Let [tex]\hat p[/tex] = sample proportion of three-point field goals made in one season.
The z-score probability distribution for the sample proportion is given by;
Z = [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}} }[/tex] ~ N(0,1)
where, p = population proprotion of three-point field goals = 37.9% = 0.379
n = sample of three-point field goal attempts = 80
[tex]\hat p[/tex] = sample proportion of three-point field goals = [tex]\frac{35}{80}[/tex] = 0.4375
Now, if 80 three-point field goal attempts are randomly selected from the season, the probability that more than 35 were made is given by = P([tex]\hat p[/tex] > 0.4375)
P([tex]\hat p[/tex] > 0.4375) = P( [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p(1-\hat p)}{n}} }[/tex] > [tex]\frac{0.4375-0.379}{\sqrt{\frac{0.4375(1-0.4375)}{80}} }[/tex] ) = P(Z > 1.05) = 1 - P(Z [tex]\leq[/tex] 1.05)
= 1 - 0.85314 = 0.14686
The above probability is calculated by looking at the value of x = 1.05 in the z table which has an area of 0.85314.

In the sequence 2001, 2002, 2003, ... , each term after the third is found by subtracting the previous term from the sum of the two terms that precede that term. For example, the fourth term is 2001+2002−2003=2000. What is the 2004th term in this sequence?
Answer:
The answer is 0.
Step-by-step explanation:
Let's call the answer a.
We want to find a(2004)
That's an even term. We look at the even terms:
2 2002
4 2000
6 1998
8 1996
10 1994
12 1992
We see that the pattern for the even terms is
"if you add n and a(n), the sum is always 2004."
That is n + a(n) = 2004, or,
a(n) = 2004-n when n is even
So when n = 2004, a(2004) = 2004-2004 = 0
Answer: 0
