Answer:
3.5
Step-by-step explanation:
Denote points:
- G - gas station;
- M - motel;
- S - sister's home.
These three points lie on the same line in order M, G and S. The distance MS=341 mi and MS=GM+GS.
It takes Doug 3 hours to go to a motel from gas station (GM) and it takes 2.5 hours Ashley to go to a sister's home from gas station (GS). The total time is 3+2.5=5.5 hours.
Then using the formula d=rt, you can conclude that
341=5.5·r,
r=341:5.5,
r=62 mi/h.
Answer: 62 mi/h.
Answer:
x = 12
consider this a straight line:
A B C
-------------------------------------------------
<u>solve for AB</u>:
⇒ AB = AC - BC
⇒ AB = 2x - 7 - ( x - 3 )
⇒ AB = 2x - x - 7 + 3
⇒ AB = x - 4
<u>solve for x</u>:
⇒ x - 4 = 8
⇒ x = 8 + 4
⇒ x = 12

Answer:
Step-by-step explanation:
the volume of this prism is equal to
V=l*w*h
V=(x+1)(x)(x-3)
multiply
V=x^3-2x^2-3x
it is your first choice
