Answer: the answer is the first one ,the third one , and the fourth
Step-by-step explanation:5x5 25
15x15 225
Answer:
x ≤ 1 and x ≥ −15
Step-by-step explanation:
<u>Solving Absolute Value</u>
- We know that x + 7 ≤ 8 or x + 7 ≥ -8
<u>Condition 1:</u>
Step 1: Subtract 7 from both sides.
<u>Condition 2:</u>
Step 1: Subtract 7 from both sides.
Therefore, the answer is x ≤ 1 and x ≥ -15.

Answer:
60 mph
Step-by-step explanation:
We don't know how far Jimmy drives in each direction. Let this distance be d. Then, d = rate * time, and d = r(2 hours) (where r represents his speed while driving to the ferry).
But it's also true that d = (r - 20 mph)(3 hours).
Equating d = r(2 hours) and d = (r - 20 mph)(3 hours), we get:
r(2) = (r - 20)(3), or 2r = 3r - 60.
Subtracting 2r from both sides yields 0 = r - 60, so that r = 60 mph.
Jimmy averaged 60 mph on the outbound trip.
Answer:
92.5
Step-by-step explanation:

cross multiply:
18.5 · 500 = 9250
100 · x = 100x
isolate x by dividing 100 from both sides:
x = 92.5
hope this helps!
