Question

Given the equation, d=m/v. if d=3/6 and v=m+3, then m= ?
1
3
-3

Answer 1

m = 3

Explanation:

d =
`(m)/(v)` ( multiply both sides by v )

dv = m

substitute given values for d and v

m =
`(3)/(6)` (m + 3) =
`(1)/(2)` (m + 3) ← multiply both sides by 2 to clear the fraction

2m = m + 3 ( subtract m from both sides )

m = 3
