Question

Mia says that when you rearrange 3a - p = m to make a the subject of the formula you get:

Answer 1

Answer:

$a =\frac{m+p}{3}$

Step-by-step explanation:

$3a - p = m$

→ First plus p to both sides to isolate 3a

$3a = m+p$

→ Divide both sides by 3 to isolate a

$a =\frac{m+p}{3}$

Answer 2

Answer:

see explanation

Step-by-step explanation:

Mia is wrong in that she has subtracted p from both sides instead of adding p to both sides.

Given

3a - p = m ( add p to both sides )

3a = m + p ( isolate a by dividing both sides by 3 )

a = $\frac{m+p}{3}$
