Answer:
i belive there is no solution
Step-by-step explanation:
Y=kx+b
2k+b=-1
6k+b=1
6k+b-2k-b=2
4k=2
k=1/2
b=-2
y=1/2x-2
So your answer is option A
Answer:
x = 3/8
y = -7/8
Step-by-step explanation:
y = -5x + 1
5x + y = 1
y = 3x - 2
-3x + y = -2
Elimination
5x + y = 1
-3x + y = -2
__________--
8x = 3
x = 3/8
5x + y = 1 | ×3 |
-3x + y = -2 | ×5 |
15x + 3y = 3
-15x + 5y = -10
____________+
8y = -7
y = -7/8
Answer:
answer is 6/25
Step-by-step explanation:
6/25 x 100% = 24%
Quantity of paint left =
gallons
Solution:
Quantity of yellow paint =
gallons
Quantity of green paint =
gallons
Quantity of blue paint =
gallons
Quantity of paint used =
gallons of each paint
Quantity of paint left =
gallons of each paint
Quantity of paint left = ![(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}](https://tex.z-dn.net/?f=%28%5Cfrac%7B6%7D%7B5%7D%2B%5Cfrac%7B7%7D%7B6%7D%2B%5Cfrac%7B7%7D%7B8%7D%29%5Ctimes%5Cfrac%7B1%7D%7B4%7D)
Taking LCM for 5, 6, 8, we get LCM = 120
![(\frac{6}{5}+\frac{7}{6}+\frac{7}{8})\times\frac{1}{4}=(\frac{144}{120}+\frac{140}{120}+\frac{105}{120})\times\frac{1}{4}](https://tex.z-dn.net/?f=%28%5Cfrac%7B6%7D%7B5%7D%2B%5Cfrac%7B7%7D%7B6%7D%2B%5Cfrac%7B7%7D%7B8%7D%29%5Ctimes%5Cfrac%7B1%7D%7B4%7D%3D%28%5Cfrac%7B144%7D%7B120%7D%2B%5Cfrac%7B140%7D%7B120%7D%2B%5Cfrac%7B105%7D%7B120%7D%29%5Ctimes%5Cfrac%7B1%7D%7B4%7D)
![=(\frac{389}{120})\times\frac{1}{4}](https://tex.z-dn.net/?f=%3D%28%5Cfrac%7B389%7D%7B120%7D%29%5Ctimes%5Cfrac%7B1%7D%7B4%7D)
![=\frac{389}{480}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B389%7D%7B480%7D)
Hence, Mark will have
gallons of paint left after painting the mural.
