Apply the distributive property to create an equivalent equation.
3(2m + 7) = -5(6 + m)

6m + 42 = -30 - 5m

Step-by-step explanation:

distribute 3(2m+7) = -5(6+m)

6m + 42 = -30 - 5m

m=-51/11

Step-by-step explanation:

3(2m+7)=−5(6+m)

Simplify both sides of the equation.

3(2m+7)=−5(6+m)

(3)(2m)+(3)(7)=(−5)(6)+(−5)(m)

6m+21=−30+−5m

6m+21=−5m−30

Add 5m to both sides.

6m+21+5m=−5m−30+5m

11m+21=−30

Subtract 21 from both sides.

11m+21−21=−30−21

11m=−51

Divide both sides by 11.

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
