As shown in the model below, there are three lines.
Answer:
<
Explanation:
turn 5/11 into a decimal: 0.45 which is LESS than 0.50 (0.5).
Given that the dealer sells a dozen tires for $240, every 3-tire set costs $60. There are six 2-tire sets in a dozen. Thus, his total revenue should be $360. The total profit is the difference between the total revenue and the total cost. The answer is therefore, the first choice, $120.
Answer + Explanation:
let x be the measure of angle x
let y be the measure of angle y

Now, solve:
plug x = 24 + y into x + y = 180
24 + y + y = 180
24 + 2y = 180
2y = 156
y = 78
Now, plug this back into the equation x = 24 + 78
x = 102
Total marks C needs to get = 92 x 4 = 368
Least grade (fourth quarter) = 368 - 88 - 91 - 90 = 99
