I need help with finding m & I’m pretty sure exercise 6 is # 6 help please

Answer 1

$\text{Hello!}$

=+=+=+=+=+=+=+=+=+=+=

$\text{Formula: } \boxed{5/4n - 7 = m}$

$\text{ When n = 40, } \boxed{m = 43}$

$\text{ Isolate for m:}$

$\text{Begin by dividing both sides by 4/5 (multiply by reciprocal):}$

$n = 4/5(m + 7 ) \text{ becomes } 5/4n = m + 7$

$\text{Subtract 7 from both sides to isolate "m"}$

$5/4n - 7 = m$

$\text{Substitute n = 40 into the equation to solve for "m":}$

$5/4(40) - 7 = m\\\\50 - 7 = m\\\\m = 43$
