Answer & Step-by-step explanation:
The ratio of square feet to gallons of paint:
![1440:6](https://tex.z-dn.net/?f=1440%3A6)
This can also be written as:
![\frac{1440}{6}](https://tex.z-dn.net/?f=%5Cfrac%7B1440%7D%7B6%7D)
This fraction can be simplified by dividing the numerator and denominator by 6:
![\frac{1440}{6}=\frac{240}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B1440%7D%7B6%7D%3D%5Cfrac%7B240%7D%7B1%7D)
So, the ratio of square feet to gallons of paint is:
1 gallon for every 240 ft².

Answer:
105.
Step-by-step explanation:
21+21+21+21+21=105.
Answer:
Step-by-step explanation:
Isolate any variable, x or y, but since y has already been isolated, use y to solve for x.
Substitute y into the first equation -3x-3y=3
This equals -3x - 3 (-5x - 17) = 3
Distribute to get -3x + 15x + 51 = 3
Then bring like terms together. -3x + 15x = 3 - 51
12x = -48
Solve for x
x = -4
Substitute -4 for x in the equation: y = -5x - 17
y = − 5x − 17
y = (−5) (−4) − 17
y = 20 - 17
y = 3 ( Simplify both sides of the equation)
Answer:
x = − 4 and y = 3
Answer:
T = 36
Step-by-step explanation:
T = 5(4.2)-6(-2.5)
T = 21 + 15
T = 36
