Question

Given the Equation, D = m/v, if D = 1/4 and v = m + 3, then m =

1
-3
2

Answer 1

m = 1

substituting the given values for D and v the equation can be expressed as

`(1)/(4)` =
`(m)/(m+3)` (cross- multiply )

4m = m + 3 ( subtract m from both sides )

3m = 3 ( divide both sides by 3 )

m = 1 ← first value on list
