Answer:
12.5%
Step-by-step explanation:
First we need to calculate the change in the area of Terry's room this is
108 ft2 - 96 ft2 = 12 ft2
Then we use a direct proportion in order to find the percentage
96 ft2 ----- 100%
12 ft2 ----- p?
Solvin for p we have that
p=12.5
Both are equal y. So you can set them equal to each other
9x+13=2x+48
Subtract 2x from both sides
7x+13=48
Subtract 13 from both sides
7x= 35
X=5
Answer:
One of the Numbers is -151 and the other is -144
Step-by-step explanation:
Set up the equations then solve
In step 2 the 6(1 * x) is supposed to be 6 * 6x.
C = -840
Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840
