Step-by-step explanation:
Answer:
39. r = 13.4
40. m = 12
Step-by-step explanation:
39. Given the equation,
, to solve for r, the following are the correct steps to take to arrive at the solution:
(given)
Add 0.8 to both sides of the equation (addition property of equality)
(this is where the error occurred.)

40. The correct steps to take in solving the equation,
is as follows:
(given)
Multiply both sides by 3 (multiplication property of equality)

(this is where the error occurred. This is what we should have at this line/step)
(dividing both sides by -1)
Answer:
66.7%
Step-by-step explanation:
The factors of 18 are as listed: 1, 2, 3, 6, 9, 18
Since 1, 2, 3, and 6 are in the die, that makes 4 out of the 6 numbers.
4/6 can be simplified to .667 or 66.7%
