Question

8×(27m+27)+5×(31-17m)=448

Answer 1

Ответ:

Пошаговое объяснение:

216м+216+155-85м=448

216м-85м=448-216-155

131м=77

м=77:131

м=0,5877862595419847=0,6(примерно)

Answer 2

Let's solve the equation step by step.

8 × (27m + 27) + 5 × (31 - 17m) = 448

First, we simplify the expressions inside the parentheses:

8 × 27m + 8 × 27 + 5 × 31 - 5 × 17m = 448

Multiply the coefficients with the terms inside the parentheses:

216m + 216 + 155 - 85m = 448

Combine like terms:

(216m - 85m) + (216 + 155) = 448

131m + 371 = 448

Next, isolate the variable term by subtracting 371 from both sides of the equation:

131m = 448 - 371

131m = 77

Finally, divide both sides of the equation by 131 to solve for m:

m = 77 / 131

m ≈ 0.5878

So, the solution to the equation is m ≈ 0.5878.
