45/3 = 15 calories every hour
Answer:
No.
Step-by-step explanation:
If you simplify the first problem, ( 9(4-x)) It would equal 36-9x. While they may be close one has an addition sign and the other has a minus sign.
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.
Answer:
You need the minimum cost for renting the meeting room given the following info
Reservation Fee = $18
Hourly Rate = $5
The renter wants to keep the cost below $58
So the cost will vary with the time, t you use the inequality below
5t + 18 ≤ 58
You can solve this to get that minimum
You can check you answer by graphing it.
