Question

Given the proportion 8/5 = 2/m-3 what is the value of m

Answer 1

Hey there! :)

Answer:

m = 4.25, or 17/4.

Explanation:

Given the proportion:

`(8)/(5)= (2)/(m-3)`

Cross multiply:

8(m - 3) = 5 · 2

Distribute the 8:

8m - 8(3) = 10

8m - 24 = 10

Add 24 to both sides:

8m = 34

Divide both sides by 8:

8m/8 = 34/8

m = 4.25, or 17/4.
