ERROR ANALYSIS In Exercises 39 and 40, describe and

expeople1 [14]

Answer:

39. r = 13.4

40. m = 12

Step-by-step explanation:

39. Given the equation, $-0.8 + r = 12.6$ , to solve for r, the following are the correct steps to take to arrive at the solution:

$-0.8 + r = 12.6$ (given)

Add 0.8 to both sides of the equation (addition property of equality)

$-0.8 + r + 0.8 = 12.6 + 0.8$ (this is where the error occurred.)

$r = 13.4$

40. The correct steps to take in solving the equation, $-\frac{m}{3} = -4$ is as follows:

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

Multiply both sides by 3 (multiplication property of equality)

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

$-m = -12$ (this is where the error occurred. This is what we should have at this line/step)

$m = 12$ (dividing both sides by -1)
