Answer 1

Answer:

I hope you understand this

Answer 2

The value of M = 3

Step-by-step explanation:

$2(2m + 1) – 40 \: \% \: of (6m – 1) = 7.2 \\ \\ (4m + 2) - \frac{40}{100} \times (6m - 1) = 7.2 \\ \\ (4m + 2) - \frac{4}{10} \times (6m - 1) = 7.2 \\ \\ \frac{(4m + 2)}{1} - \frac{(24m - 4)}{10} = 7.2 \\ \\ \frac{10 \times (4m + 2) - (24m - 4)}{10} = 7.2 \\ \\ \frac{40m + 20 - 24m + 4}{10} = 7.2 \\ \\ \frac{16m + 24}{10} = \frac{72}{10} \\ \\ cut \: denominator \: 10 \: by \: 10 \\ \\ 16m + 24 = 72 \\ \\ 16m = 72 - 24 \\ \\ 16m = 48 \\ \\ m = \frac{48}{16} \\ \\ m = 3$
