Answer:
y = 3
Step-by-step explanation:
Answer:
y= 3
Step-by-step explanation:
Can some one help me.
Answer:
The slope is 3
Step-by-step explanation:
m = rise/run
m = (y2 - y1)/(x2-x1)
points: (0,-5), (1,-2)
m = ((-5) - (-2))/ ((0) - (1))
m = (-5 + 2)/ (-1)
m = -3/-1
m = 3

£760 is divided between Stephen, Bridget & Caroline so that Stephen gets twice as much as Bridget, and Bridget gets three times as much as Caroline. How much does Bridget get? £
Answer: Out of £750 and 3 bums
Caroline = 225
Bridget = 225 * 3 = 675
Step-by-step explanation:
Answer:
£228Step-by-step explanation:
Given:
Total = £760Stephen = s, Bridget = b, Caroline = cWe have equations:
s + b + c = 760b = 3cs = 2bSubstitute s with b and b with c as above into first equation:
2(3c) + 3c + c = 7606c + 4c = 76010c = 760c = 76Find b:
b = 3*76 = 228Bridget gets £228

The area of a triangle is 2x^2 - 11x + 15 square meters. The length of the base of the triangle is 2x-5
meters. What is the height of the triangle?
Answer:
of triangle =12base×height
Area of triangle =2x2−11x+15
base =2x−5
Plugging in the given;
2x2−11x+15=12(2x−5)×height
2x2−11x+15=2x−52×height
2x2−11x+151=2x−52×height
2(2x2−11x+15)=(2x−5)×height
4x2−22x+30=(2x−5)×height
4x2−22x+302x−5=height
Resolving the quadratic equation;
(4x2−22x+30)
Simplifying;
4x
Answer:
2x-6
Step-by-step explanation:
height : 2(2x^2-11x+15)/(2x-5)
(4x^2-22x+30)/(2x-5)
Δ/4 = 121 - 120 = 1
x1 = (11+1)/4 = 3
x2 = (11-1)/ 4 = 5/2
4(x-5/2)(x-3)
(4x-10)(x-3)/(2x-5)
2(2x-5)(x-3)/(2x-5)
2x-6
Proof
(2x-6)(2x-5)/2
2(x-3)(2x-5)/2
2x^2-5x-6x+15
2x^2-11x + 15
ill give u the crown thingy pls help
Answer:
y=18 x=15
Step-by-step explanation:
1.
multiplyboth sides by 3
2(x-6)=18
divide both sides by 2
x-6= 9
add 6 on both sides
x=15
2.
add 6 on both sides
2/3y= 12
multiply both sides by 3
2y=36
divide both sides by 2
y=18

James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20. James has dimes
The question is incomplete:
James has dimes and quarters saved up in his change jar. He has a total of 162 coins totaling $31.20 what is the total amount james has in quarters?
a. $10.00
b. $6.20
c.$15.50
d.$25.00
Answer:
d.$25.00
Step-by-step explanation:
With the information provided, you can write the following equations given that dimes are equal to 0.10 and quarters to 0.25 to determine the number of dimes and quarters that James has:
x+y=162 (1)
0.10x+0.25y=31.20 (2), where:
x is the number of dimes
y is the number of quarters
First, you can solve for x in (1):
x=162-y (3)
Then, you have to replace (3) in (2) and solve for y:
0.10(162-y)+0.25y=31.20
16.2-0.10y+0.25y=31.20
0.15y=31.20-16.2
0.15y=15
y=15/0.15
y=100
Finally, you have to replace the value of y in (3) to find x:
x=162-100
x=62
Now, you know that James has 100 quarters and you can multiply this number for the value of a quarter to find the amount James has in quarters:
100*0.25=25
According to this, the answer is that James has $25 in quarters.

Mom can make 10 brounies in a 12 ounce pacge the bags are sold in one and a half bag how much would she need to make 120
Answer:
Question is: Mom can make 10 brownies from a 12-ounce package. The brownie mix is also sold in 1 and a half-pound bags. How many bags would be needed to make 120 brownies?
Step-by-step explanation:
As mentioned in question,
10 brownies made from = 12 ounce package
120 brownies will be made from = 10 * 12 packages
now 12 packages will have ounces = 12 * 12 = 144 ounces
We also know that packages are one and a half pounds
Applying conversion factor = 1.5 pound = 24 ounces
Now we can find answer: 144 ounces total requires / 24 ounces
Answer = 6 bags
6 bags of 1.5 pounds will be required for 120 brownies.

30 points!!! Find the area of each. Round to the nearest tenth. Do not include units in
your answer (ie. ft, in, km, etc)(triangle-FR) *
Answer:
Area of triangle = 8.9
Area of parallelogram = 53.4 yd² (option A)
Step-by-step explanation:
✔️Area of the triangle = ½*base*height
base = 3 m
height = 5.9 m
Area of triangle = ½*3*5.9
Area of triangle = 8.85 ≈ 8.9 (nearest tenth)
✔️Area of parallelogram = base*height
base = 8.9 yd
height = 6 yd
Area of parallelogram = 8.9*6 = 53.4 yd²
I need help with my homework
please help i’m not tryna fail algebra i can’t figure this out(solve by substitution and show steps please)
Answer:
y=8-6x
Step-by-step explanation:
Answer:
y=0
x=4/3
Step-by-step explanation:
6x+y=8
x =8-y/6
substitute 8-y/6 in second equation
42*8-y/6 +7y=56
7(8-y) +7y=56
56-y+ 7y=56
-y+ 7y=0
6y=0
y=0
6x+y=8
6x+0=8
x=8/6
x=4/3

A tree that is 4 ft tall is growing at a rate of 1 ft each year a tree that is 12 feet tall is growing at a rate of 1/2 ft each year how many years will it take the two trees to reach the same height
Answer:
16 years
Step-by-step explanation:
Given data
For the first tree
let the expression for the height be
y=4+x--------------1
where y= the total height
4= the initial height
x= the number of years
For the second tree, the expression is
y=12+0.5x-------------2
Equate 1 and 2
4+x=12+0.5x
x-0.5x=12-4
0.5x= 8
x= 8/0.5
x=16
Hence it will take 16 years for both trees to have the same height
The distances and times from a track meet for four schools are shown.
School has the fastest average time per mile at the track meet.
Answer:
Average time for West Middle was maximum.
Step-by-step explanation:
Average time for a track meet for schools = [tex]\frac{\text{Time}}{\text{Distance}}[/tex]
For Eastbay Middle,
Average time per mile = [tex]\frac{42}{7}[/tex]
= 6 minutes per mile
For Northwest Middle,
Average time = [tex]\frac{25}{5}[/tex]
= 5 minutes per mile
For South Central Middle,
Average time = [tex]\frac{28}{4}[/tex]
= 7 minutes per mile
For West Middle,
Average time = [tex]\frac{48}{6}[/tex]
= 8 minutes per mile
Therefore, average time for West Middle (8 minutes per minute) was maximum.

Answer:
25 is the answer
for proof see the pic
first divide it by 11 then and when you get the numerator as 100 and denominator as 4 divide it by 2
So as to get numerator as 50 and denominator as 2 .
Later, Divide it by 2 and hence, your answer is 25.....;)
Somebody please help me
Answer:
169 [tex]cm^2[/tex]
Step-by-step explanation:
The surface area is the two-dimensional distance around a figure. In essence, if one was going to wrap the figure in paper, the surface area would be the amount of paper one would need. To find the surface area, one would have to find the area of each individual face, and add up the values.
(7) * (5) = (35)
(9) * (5) = (45)
(7) * (5) = (35)
([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)
([tex]\frac{1}{2}[/tex]) * (6) * (9) = (27)
Add up all of the values:
(35) + (45) + (35) + (27) + (27) = 169
Consider a collection of envelopes consisting of 3 red envelopes, 1 blue envelope, 2 green envelopes, and 3 yellow envelopes. If two envelopes are selected at random, with replacement, determine the probability that at least one envelope is a red envelope.
Answer: The probability that at least one of the envelopes is red is 1/9 (simplified) or 9/81.
Step-by-step explanation:
There are a total of 9 envelopes. If two are selected at random with replacement the probability for both envelopes is 3 / 9 or 1/3. Since there are two you would do 1/3 * 1/3 to get 1/9 or 3/9 * 3/9 to get 9/81.

Step-by-step explanation:
Daniel deposits a certain sum of money in a bank. If the simple interest rate of the bank decreases from 3.75% per annum to 3.5% per annum, Daniel's interest will increases by $50 in a year. Find the sum of money he deposits.
The answer is $20000 but I don't understand how. Please give a step-by-step explanation.
Answer: $20,000
Step-by-step explanation:
Given
Interest decreases from 3.75% to 3.5% in a year
This change in the rate of interest brings a yield of 50$
Earlier interest was
[tex]S.I_e=\dfrac{P\times 3.75\times 1}{100}[/tex]
Now, interest is
[tex]S.I._n=\dfrac{P\times 3.5\times 1}{100}[/tex]
change gives 50$ i.e.
[tex]\Rightarrow \dfrac{P\times 3.75\times 1}{100}-\dfrac{P\times 3.5\times 1}{100}=50\\\\\Rightarrow \dfrac{P\times (3.75-3.5)\times 1}{100}=50\\\\\Rightarrow P=\dfrac{50\times 100}{0.25}=\$20,000[/tex]
