how to solve 9x-5-(-6x)
Answer: 3x-5
Step-by-step explanation:
9x-5(-6x)
9x-5-6x
3x-5
Answer:
15x - 5
Step-by-step explanation:
We have the equation 9x - 5 - (-6x) and are asked to solve it.
We cannot combine 9x and 5 because they have a variable difference, with 9 having x as its variable and 5 having no variable. What we can do is distribute the minus sign to the right of 5 to (-6x), lets do as said :
9x - 5 - (-6x)
Two negatives make a positive, therefore :
9x - 5 + 6x
Since 9x and 6x have the same variable ending, we can combine them, do as followed :
9x - 5 + 6x
9x + 6x
15x - 5
your friend decides to toast a piece of bread, but leaves it in the toaster too long. the bread is black and the kitchen is full of smoke.
is the change chemical or physical. and give evidence
Answer:
Chemical because there is a change in color and the smoke is a change of substance.
Step-by-step explanation:
Answer:
Chemical.
Explanation:
So, before the bread was the normal color like all breads are, but then the bread was in the toaster for way to long. It started to turn black. Therefore, the change of color would be a chemical change.
Also this is the wrong subject. I'm pretty sure it's supposed to be Biology.

Answer:
7, 10
Step-by-step explanation:
X - 1 is greater than or equal to 6
+1. +1
x is greater than or equal to 7.
7 can work as
7 - 1 is greater than or equal to 6
6 is greater than or equal to 6
10 also works because if you put it in the equation the answer is still more than 6.
2/3 - 3/2y + 1/3y + 4 = 0
Answer:
y = 4
Step-by-step explanation:
(2/3 + 4) + (-3/2y + 1/3y) = 0
(-3/2y + 1/3y) = -4 2/3
-9/6y + 2/6y = -14/3
-7/6y = -14/3
cross-multiply:
-21y = -84
y = 4
Answer:
y = 4
Step-by-step explanation:
Please use parentheses for clarity, remembering what big differences they make in expression values.
I will assume that your "2/3 - 3/2y + 1/3y + 4 = 0" actually means
2/3 - (3/2)y + (1/3)y + 4 = 0
The LCD here is 6, which is the product of the denominators 2 and 3.
Then your "2/3 - 3/2y + 1/3y + 4 = 0" becomes:
4 - 9y + 2y + 24 = 0, which simplifies to:
28 - 7y = 0. Solving this, we get y = 4
If the interest of a sum of money in 6years is 3 by 8 of the principal what is the rate of interest
Answer: rate of interest (r) = 6.25
Step-by-step explanation:
Simple interest formula is S.I = PxTxR/100
From the question ;
S.I = (3/8) principal
3/8p = px6xr/100
Eliminate p on both sides of the equation
r = (3x100) / (8 x 6)
r = 300 / 48
r = 6.25

A 12 feet tall street light is making an 18 feet shadow at the same time in nearby building is making a 72 feet shadow
Answer: 48 ft
Step-by-step explanation:
Given
Height of street light h=12 ft
length of shadow x=18 ft
Shadow length of building x'=72 ft
suppose the height of the building is y
from the figure, we can write
[tex]\Rightarrow \tan p=\dfrac{h}{x}=\dfrac{12}{18}\\\\\Rightarrow \tan p=\dfrac{y}{x'}=\dfrac{12}{18}\\\\\Rightarrow y=72\times \dfrac{2}{3}=48\ ft[/tex]

Answer:
375.2887 ft is the answer
Answer:
375.3 ft
Step-by-step explanation:
What we need to do first is divide 175 by the sine of 25°.
175/sin(25°)
175/0.422618
175/1 * 500000/211309
25/1 * 500000/30187
12500000/30187
414.085534 = length of hypotenuse.
Now, find the square root of the difference between c² & a².
b = √414.09² - 175²
b = √171470.528 - 30625
b = √140845.528
b = 375.293922
b ≈ 375.3

Mount McKinley, in Alaska, is about 3.848 miles high. If a mountain climber can climb 0.25 miles per day, about how long to the nearest day, would it take to climb Mount McKinley?
Answer:
About 16 days.
Step-by-step explanation:
The mountain is 3.848 miles high and you climb 0.25 miles a day. So you have to divide 3.848 by 0.25 and you get 15.392. But since you have to round it to the nearest day, you round it up to 16 because if you round down to 15 you still have 0.392 of a day leftover.

Step-by-step explanation:
Researchers studying the sticky droplets found on spider webs will measure the widths of a random sample of droplets. From the sample, the researchers will construct a 95 percent confidence interval to estimate the mean width of all such droplets. Write the correct statement about a 95 percent confidence interval for the mean width.
Answer:
The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
The confidence interval can be obtained using the relation :
Xbar ± Margin of error
Margin of Error = Zcrit * s/sqrt(n)
Zcritical = critical vlaue at the specified α - level
n = sample size ; s = standard deviation
Sample size being the denominator, will reduce the overall value of the error margin as we utilize a larger sample.
Hence, the interval becomes narrower as the error margin is reduced which is achieved by employing an increased sample size.
Answer:
B. The interval will be narrower if the researchers increase the sample size of droplets.
Step-by-step explanation:
B. The interval will be narrower if the researchers increase the sample size of droplets.
Margin of error of a confidence interval:
The higher the margin of error, the wider an interval is.
In which z is related to the confidence level(the higher the confidence level, the higher z), is the standard deviation of the population and n is the size of the sample.
From this, we conclude that:
If we increase the confidence level, the interval will be wider.
If we increase the sample size, the interval will be narrower.
Which of the following statements about a 95 percent confidence interval for the mean width is correct?
Increasing the sample size leads to a narrower interval, so the correct answer is given by option B.
Can someone help me I give you 10 points
Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
Angela painted 4 pictures in 7 days. She paints additional pictures at the rate of 1 per day. Which recursive function gives the total number of pictures she will have painted at any day in the future? How many pictures will she have painted if she paints for another 5 days after the initial week?
Answer:
The recursive function gives the total number of pictures Angela will have painted at any day in the future is:
PP(t) = t + [tex]\frac{4}{7}t[/tex]The number of pictures will she have painted if she paints for another 5 days after the initial week is:
18.86Step-by-step explanation:
To obtain the recursive function, you must take into account the next:
1. Angela paints 4 pictures in 7 days, by this, you can say Angela paints 4/7 of a picture by day.
2. Angela paints additional 1 picture by day, with this, the number of pictures painted additionally is equal to the time t (because 1 day = 1 picture, 2 days = 2 pictures and so on). With the data taken into account, we can elaborate the next function:
PP(t) = t + [tex]\frac{4}{7}t[/tex]Where:
PP: Painted pictures.t: time in days.For example, if you need to know how many pictures she painted in the first week, you can calculate replacing t by 7:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(7) = 7 + [tex]\frac{4}{7}*7[/tex]PP(7) = 7 + 4PP(7) = 11If she paints for another 5 days (I mean 12 days taking into account the initial week), we can calculate:
PP(t) = t + [tex]\frac{4}{7}t[/tex] PP(12) = 12 + [tex]\frac{4}{7}*12[/tex]PP(12) = 12 + [tex]\frac{48}{7}[/tex]PP(12) = [tex]\frac{132}{7}[/tex]PP(12) = 18.86To the day 12, Angela will paint 18.86 pictures.
Answer:
The recursive function that gives the total number of pictures she will have painted at any day in the future is
next = now + 1, starting at 4 , and the total number of pictures after a week plus 5 days is 9.

y = 3x + 3
y = x − 1
Answer:
Step-by-step explanation:
Well you have to solve for X to find Y simplified.
Since both equations equal Y you can plug them together
3x+3=x-1
-x -x
2x+3=-1
-3 -3
2x=-4
Divide -4 by 2 and you get X = -2 then plug X into both equations and boom

A contractor decides that he can build a barn in nine weeks using four men. If he employs two more men, how long will the job take? Assume that all the men work at the same rate.
Answer: 6weeks
Step-by-step explanation:
If it takes 4 men, 9 weeks to build a barn.
It will take a man; 4 x 9weeks =36 weeks to make a barn
If it takes a man 36weeks to make a barn, it will take 4men + 2 men i.e 6men = 36/6
6 weeks to make a barn
The long will the job take:
If it takes 4 men, 9 weeks to build a barn. It will take a man; 4 x 9weeks =36 weeks to make a barn If it takes a man 36weeks to make a barn, it will take 4men + 2 men i.e 6men = 36/6Thus,by adding two more men it will take 6 weeks to make a barn.
