Answer:
45
Step-by-step explanation:
Since the lines of hypotenuse are parallel,the triangles are similar
20/8 = x/18
cross multiplication
8x = 20x18
8x=360
x=45

Answer:
7 weeks
Step-by-step explanation:
b=95+(10+9)w
Combine like terms
b=95+(19)w
Let b = 220
220 = 95 + 19w
Subtract 95 from each side
220-95 = 19w
125 = 19w
Divide each side by 19
125/19 = w
