Answer:
14.5
Step-by-step explanation:
[tex] \frac{2}{7} = \frac{5}{m + 3} [/tex]
[tex]2(m + 3) = 7 \times 5[/tex]
[tex]2m + 6 = 35[/tex]
[tex]2m = 35 - 6[/tex]
[tex]2m = 29[/tex]
[tex]m = 14.5[/tex]
m = 14.5
[tex]\frac{2}{7}[/tex] = [tex]\frac{5}{m+3}[/tex] ( cross- multiply )
2(m + 3) = 35
2m + 6 = 35 ( subtract 6 from both sides )
2m = 29 ( divide both sides by 2 )
