Answer:
2 Gallons.
Step-by-step explanation:
If 8 gallons are lost in one hour, then 4 will be lost in 30 minutes. Half of thirty minutes is 15 minutes, and half of 4 is 2.
Because there's an even number of values in this set, there is two middle values rather than one (31 and 34). To find the median we need to add them together and divide the sum by 2 (31 + 34 = 65, 65/2= 32.5) Our final answer is 32.5.
Add those equations together
<span>1. 4x = 16, x = 4
2. Multiple the second one by 2
2x+4y=22
4x-4y=-16
6x = 6, x = 1
3. Add them together
8x = 24, x = 3

Answer:
80 minutes
Step-by-step explanation:
The ratio can be simplified and rewritten:
minutes : miles = 24 : 3 = 8 : 1 = 80 : 10
It will take Josie 80 minutes to run 10 miles at her 8 minutes/mile pace.
N+4=13
-4 -4
n = 9
the sum of a number(n) and 4 that is no larger than 13 is 9
