Answer: 25
Step-by-step explanation:
Both lines are being cut by the same transversal so to solve for x, make both equations equal to each other
2x+10 = 3x-15
To isolate x, do the inverse operations (for any side chosen)
Do the inverse operations to move -15 and isolate 3x
Add 15 to 10 (10+15=25)
You now have 2x+25=3x
Now, do the same to combine the x values together
25=3x-2x
You now have 25=1x
Divide by 1 on both sides
25=x

Answer:
Abelito had the greater average speed
Step-by-step explanation:
Given
Bobby:
Abelito
Required:
Who had a greater average speed
Average speed (S) is calculated as:
We will make use of mph (miles per hour) as the unit of speed.
For Bobby:
Convert minute to hour
For Abelito
Convert minute to hour
By comparison: 12.5mph > 8mph
Hence: Abelito had the greater average speed
