Answer:
161,460 gallons are used in a year.
Step-by-step explanation:
1 shower- 2.3×15=34.5
Number of minutes spent in the shower in a week- 15×6=90
Gallons used per week- 34.5×90=3,105
There is 52 weeks in a year.
52×3,105=<u>161,460</u>
Step-by-step explanation:
5 log₅ x − ¼ log₅ (8−x)
log₅ x⁵ − log₅ (8−x)^¼
log₅ x⁵ − log₅ ∜(8−x)
log₅ (x⁵ / ∜(8−x))
X - Jack's age
y - Susan's age
Jack is 27 years older than Susan.

In 5 years he will be 4 times as old as she is.

The system of equations:

Jack is 31 years old and Susan is 4 years old.
You would need 19.5 cups of oats and 7.8 cups of sugar because 195 divided by 25 is 7.8 so then you just multiply the both of them by that
