Drag each equation to show if it could be a correct first step to solving the equation 3(6 + x) = 24. 18 + x =24 18 + 3x=24 3(6 + x) =72 ( 3 x 6 ) + ( 3 X x ) =24 6 +3x = 24 6 +x = 8 Yes No Not Enough Information

(3×6) + (3×x) = 18       ←  1st Step

Step-by-step explanation:

3(6+x) = 18

Expanding brackets by distributive property

=> (3×6) + (3×x) = 18       ←  1st Step

Multiplying

=> 18 + 3x = 18                ← 2nd Step

Subtracting 18 to both sides

=> 3x = 24-18                  ← 3rd Step

=> 3x = 6                         ← 4th Step

Dividing both sides by 3

=> x = 2                            ← 5th Step

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
