Answer:
150 miles
Step-by-step explanation:
let m represent miles
$70 + .70m = $40 + .90m
subtract 40 from each side
$30 + .70m = .90m
subtract .70m from each side
$30 = .20m
divide both sides by .20
150 = m
3y-20+x+13=3x+9
3y-20+x+13+2y=180
3y-7+x=3x+9
3y=2x+16
y=2/3x+16/3
5y+x=187
5(2/3x+16/3)+x=187
10/3x+80/3+x=187
13/3x=481/3
x=37
Answer:
The equation
gives average time spent on 35 rehearsals.
Step-by-step explanation:
We are supposed to find that what question does the equation
finds answer of.
We can see that 35x represents time spent on 35 rehearsals and
is time spent on other responsibilities related to play. The sum of these times equals to total time spent on preparing the play.
Now let us solve our equation step by step.
After subtracting
hours from 190 hours we will get time spent on 35 rehearsals.


Time spent on 35 rehearsals is 96.25 hours and we are told that each rehearsal took different amount of time. Dividing 96.25 by 35 we will get average time spent on each rehearsal.
Therefore, equation
finds average time spent on 35 rehearsals.
