Answer:
8 hours
Step-by-step explanation:
If Jackie wants to burn 2000 calories in one week but only burns 250 calories per hour
then, to solve how many hours you have to divide
2000/250= 8
therefor Jackie has to do aerobics for 8 hours that week to burn 2000 calories
45m+10n-30m
15m+10n
I believe this is right.

Answer:
12. (4, 7)
13. (5, -1)
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h, k).
Gas mileage = 30.5 mi/gal
Volume of gas = 1.5 l
Note that 1 liter = 0.264172 gallons
Therefore
1.5 l = (1.5 l)*(0.264172 gal/l) = 0.3963 gal
Distance traveled is (Gas mileage, mi/gal)*(Gal of gas)
= (30.5)(0.3963) = 12.087 mi
Answer: 12 mi (nearest integer)
