If m • 6 + 3 x 4 = 240, the value of m is
(1) 28
(2) 38
(3) 40
(4) 43

38

Step-by-step explanation:

The rule of PEMDAS (parentheses, exponents, multiply, divide, addition, subtraction) must be followed when solving this equation.

1. Simplify the equation

m · 6 + 3 · 4 = 240

m · 6 + 12 = 240

2. Solve for m

- subtract 12 from both sides

m · 6 = 228

- divide both sides by 6

228 ÷ 6 = 38

m = 38

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
