Answer:
x = 1/3
Step-by-step explanation:
-12x + 12 = 4 - 15x + 9
Combine like terms
-12x +12 = -15x+13
Add 15x to each side
-12x+12 +15x = -15x+15x+13
3x+12 = 13
Subtract 12 from each side
3x+12-12 = 13-12
3x = 1
Divide by 3
3x/3 = 1/3
x = 1/3
Answer:
A=80 square feet.
Step-by-step explanation:
First, we find the area of the model. 6*4=24. Now, due to the ratio of 1:40, we know that every inch is actually forty inches. So, you do this:
24*40=960.
So, the area of the actual living room is 960 inches. Or 80 feet.
3 1/2 is the length and it's a square so all of the sides are the same so i would do 3 1/2×4=
14 or 3 1/2+3 1/2+3 1/2+3 1/2=14
