Question

I need help.. but we are only doing question 34 please answer quickly

Answer 1

Answer: 33. r=13.6   34. m=12

Step-by-step explanation:

33.

-0.8+r=12.8

-0.8+r+0.8=12.8+0.8

r=13.6

34.

$\displaystyle\\-\frac{m}{3}=-4\\\\\frac{m}{-3}=-4$

Multiply both parts of the equation by -3:

$\displaystyle\\\frac{m}{-3}(-3)=(-4)(-3)\\\\ \frac{m(-3)}{-3} =12\\\\m=12$
