His car gets 21 mpg (miles per gallon). With 1 gallon he can drive 21 miles. For example, with 10 gallons, he can drive 21 mpg * 10 gal = 210 miles.
He bought $19.50 worth of gas at $1.40 per gallon.
$19.50 / ($1.40/gal) = 13.93 gal
He already had 5 gal of gas in his tanks, so now he has
5 gal + 13.93 gal = 18.93 gal
With 18.93 gal, he can drive
18.93 gal * 21 mpg = 292.5 miles

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)
