De=4x+10, ef=2x-1, and df=9x-15, find df

DE and EF are segments of the line DF, so they will add up to DF. This can be represented with this equation:

Combine like terms:

Add 15 to both sides:

Subtract 6x from both sides:

Divide both sides by 3 to get x by itself:

The value of x will be 8.

Plug this value of x into the expression for DF:

DF will equal 57.

the first question mark is 6 and the second question mark is 26 (the square root)

step-by-step explanation:

(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).
