x = - 3 3/8
Its negative 3 3/8
Step-by-step explanation:
13x + 7 = 5x - 20
Subtract 5x from both sides
8x + 7 = -20
Subtract 7 from both sides
8x = -27
Divide both sides by 8
x = -27/8
x = - 3 3/8
Answer:

Step-by-step explanation:
The old width of 4 inches became a new width of 9 inches.
Old: 4 in.
New 9 in.
The old length of 6 inches became a new length of 13.5 inches.
Divide the new size by the corresponding old size.
9/4 = 2.25
13.5/6 = 2.25
You see in both cases, the scale factor is 2.25
The scale factor is 2.25
That would be:
