Answer:

x=16

Step-by-step explanation:

From the Free Response Row,

8(15-m)=x

For the Total Time(in minutes) column

3m+x=55
x=55-3m

Since x=55-3m and x=8(15-m)

Therefore:

55-3m =8(15-m)

55-3m=120-8m

Collect like terms

-3m+8m=120-55

5m=65

Divide both sides by 5

m=13

Therefore:

x=55-3m=55-3(13)=55-39

x=16
