If Teresa drove 936 miles in 13 hours, this would mean she would have driven 72 miles every hour. 72 times 9 equals 648. After 9 hours, she would have driven 648 miles.
A = LW + 0.5bh
0.5bh = A - LW
b = (A - LW) / 0.5h
Its B

Answer:
x = 20
Step-by-step explanation:
7x° + (x + 20)° = 180° (linear pair)
Solve for x
7x + x + 20 = 180
Add like terms
8x + 20 = 180
8x + 20 - 20 = 180 - 20
8x = 160
8x/8 = 160/8
x = 20
