The formula for volume of a prism is v=(1/2bh)h so it would be
(1/2 ×7.8×4)×9= 140.4
Answer: w = -2
Step-by-step explanation:
7w = -14
Divide both sides by 7
w = -2
That was brief but hope it helps!
Answer: 10 miles.
Step-by-step explanation:
Let m the number of miles that each dog is walked.
It is given that Beth does not charge a registration fee for her dog-walking service, but she charges $5 per mile that each dog is walked.
Amount charged by Beth = 5m
Tonya’s dog-walking service charges a registration fee of $20, plus $3 per mile that each dog is walked.
Amount charged by Tonya = 20+3m
We need to find the number of miles m for which Tonya and Beth would charge the same amount.



Divide both sides by 2.

Therefore, for 10 miles Tonya and Beth would charge the same amount.

Isolate this variable, <em>x</em>,<em> </em>by dividing each side by factors that do <em>not</em> contain the variable.
