The whole wall area including the window is 150 ft squared (15 ft x 10 ft). The window is 50 square feet (5 x 10). Take the whole area and subtract the window area and you have 100 sq ft thats paintable. One can is 50 sq ft so 100/50 is 2 cans of paint needed. Your answer is H.
7(x - 4) - 3(x + 5)
Distribute the 7 and 3
7x - 28 - 3x - 15
4x - 43
Answer:
In math, value can either refer to the result of a calculation or a variable or constant
Answer:
Any number both positive or negative.
y = {all numbers}
Step-by-step explanation:
Answer:
The answers are that the x-coordinate is 3, the y-coordinate is 4 and it is in quadrant I
Step-by-step explanation:
To find these answers, start by solving the system. We can do this by multiplying the second equation by 2 and adding them together.
8x + 6y = 48
4x - 6y = -12
-------------------
12x = 36
x = 3
Next, find the y value by plugging in the x value to either equation and solving.
2x - 3y = -6
2(3) - 3y = -6
6 - 3y = -6
-3y = -12
y = 4
