"in abc, mbac = 5x + 8, mabc = 6x + 22, and mbca = 3x  25.
a. find the value of x.
b. find the measure of 3. show your work."

Actually, the answer is 12.5

5x+8+6x+22+3x+25= 180

(5x+6x+3x)+(8+22-25)= 180

14x+5=180

14x+(5-5)=180-5

14x=175

14x/14=175/14

X=12.5

Double check:

(5*12.5)+8=70.5

(6*12.5)+22= 97

(3*12.5)-25=12.5

70.5+97+12.5=180 degrees.

So, x=12.5

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.
