Question

(3×m-20):5=50 3*m-20=50*5 3*m-20=250 3*m=250+20 3*m=270 m=270:3 m=90

Answer 1

Пошаговое объяснение:

(3m-20):5=50

3m-20=50•5

3m-20=250

3m=250+20

3m=270

m=270:3

m=90

Answer 2

Your calculations are correct! Let's go through them step by step:

1. (3×m-20) / 5 = 50
2. 3*m - 20 = 50 * 5
3. 3*m - 20 = 250
4. Add 20 to both sides: 3m = 250 + 20 3m = 270
5. Divide both sides by 3: m = 270 / 3 m = 90

So, you have correctly solved for m, and m is indeed equal to 90. Good job!
