Answer:
Step-by-step explanation:
1. Subtract 7 on both sides
2. multiply by 4 on both sides
3. v = 4
I would say the original price was $512 because its now 1/4
so... 128 * 4= 512
Answer:
tan60=p/b
tan60=12/x
x=37.5
now taking sin
sin60=p/h
sin60=12/y
y=(-40) but as length can be negative so
y=40
Using distribution it would be 3m+7
