Let the speed of Brian = X
Brian drove at X miles per hour for 4 hours
Jake drove at X-15 for 4 hours
Set up an equation to get:
4x + 4(x-15) = 500 miles
Simplify:
4x + 4x -60 = 500
8x - 60 = 500
Add 60 to both sides:
8x = 560
Divide both sides by 8:
X = 560/8
X = 70
Brian's speed was x = 70 miles per hour.
Jake's speed was x - 15 = 70-15 = 55 miles per hour.
12500 people the only reason it would be a decimal is it was .524 % of 10000
Answer:
A. 49 + 16 (t - 1)
Step-by-step explanation:
Plug in t = 1 to test for the first hour:
Test as many values as you like, but testing t = 5:
You can see that plugging in just a few values confirms the answer.
I need you to send me the full question
Rounded to the nearest tenth would be one since the four isn't higher. So the answer would be 10,386.1. You did mean the tenths place right?? because could have also meant tenth(8)
