Could someone help me please if you don’t mind thank you so much!

Answer:

m = 11

Step-by-step explanation:

Given

$\frac{2}{5}$ (m + 4) = 6 ← multiply both sides by 5 to clear the fraction

2(m + 4) = 30 ( divide both sides by 2 )

m + 4 = 15 ( subtract 4 from both sides )

m = 11

This method avoids having to deal with awkward fractions
