2/9 - 7/12
First, multiply to find a common denominator. Multiply both pieces of the left fraction by 12, and both pieces of the right fraction by 9.
24/108 - 63/108 = -39/108 = -13/36
a= -13
b= 36
Answer:
2nd option: n + 5n = 42
Step-by-step explanation:
<span>First calculate the amount of overhead expenses. The selling price was $240. To find 20% of 240, multiply 240 by 0.20, which equals 48. From that, we found that the overhead expenses were $48.
To find the rate of profit, take the selling price and subtract all expenses. We know that Mr Lippman's selling price was $240, he spent $160 to buy the dryer, and he had $48 worth of overhead expenses. 240 - 160 - 48 = 32.
Therefore, the profit was $32.
To find the rate of profit, divide the profit by the total expenses. 32 / (240 + 160) = 0.08.
Therefore, the rate of profit was 8%.</span>
To find the answer to this, first, multiply 3 and 2 together, and then dividing it by 2
(3 x 2)/2
3 x 2 = 6
6/2 = 3
3 is your answer.
hope this helps
