Answer:
about 1.4 hours
Step-by-step explanation:
3.13 gallons per minute.
60 minutes in an hour, so multiply both numbers by 60.
187.8 gallons per hour.
Divide the number of gallons we need to fill the tub the number of gallons put in per hour.
255÷187.8=1.375...
Round it, you get 1.4 hours.
It takes about 1.4 hours to fill the hot tub.

Answer: <em>m = 7</em>
Step-by-step explanation: In this equation, since a -5 is being multiplied by <em>m</em>, in order to get <em>m</em> by itself, we must divide both sides of the equation by -5.
On the left side, our -5's cancel out and we are left with <em>m</em>. On the right side, -35 ÷ -5 gives us 7. So m = 7.
To check our answer, we plug 7 back in for <em>m</em> in the original equation and we get -5 (7) = -35 which is a true statement so we know our answer is correct.
