Guys can you please help Please HELP​

2x+10+3x-10=90

5x=90

x=18

the answer is 18 because the figure is a rectangle and recatngle angles equal 90

Where is I on the square?

(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
