What is the solution to this equation?

7x – 2(x – 10) = 40

7x-2x-20=40

5x-20=40

5x=40+20

5x=60

x=60/5

x=12

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
