Make m the subject of the relation: q = \;1/3(m+n) h

Correct Answer is : m= 3qh−nm = \;3q/h - nm=h3q−n

Correct Answer is : m= 3qh−nm = \;3q/h - nm=h3q−n

Question : 25

Total: 40

Make

m

q = \;\frac{1}{3}(m+n) h

Solution:

Concept:

Rearrange the given formula by inverse operations to isolate

m

on one side.

Explanation:

Start with the relation:

q = \frac{1}{3}(m+n)h

Multiply both sides by

3

to remove the fraction:

3q = (m+n)h

Divide both sides by

h

to isolate the bracket:

\frac{3q}{h} = m+n

Subtract

n

from both sides to make

m

the subject:

m = \frac{3q}{h} - n

Answer:

m = \frac{3q}{h} - n

Correct option: A.
