Jacob does the long jump for his track team. On his first jump, he jumped 7
USPshnik [31]

Answer: Jacob's second jump was 6 1/3 feet

Step-by-step explanation:

On his first jump, he jumped 7 2/3

feet. We would convert each mixed fraction to improper fraction

to enable easy addition and subtraction. Converting 7 2/3 feet to improper fraction, it becomes 23/3 feet.

His second jump was 1 1/3 feet shorter. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet.

Therefore, the distance that Jacob covered on his second jump would be

23/3 - 4/3 = 19/3 feet

Converting 19/3 feet back to mixed fraction, it becomes

6 1/3 feet

Your friend goes shopping with $35. She buys a sweater that is on sale for half price and uses a coupon for $5 off the sale pric
Artist 52 [7]
Let S = the original price of the sweater. Now, lets step through the problem...

The friend goes shopping with $35 and ends up left with $10.50. This means she spent 35 - 10.50 = 24.50 on the sweater after the sale and coupon.

Next, the sweater is on sale for 50%. This means we take S and take 50% of that. S*.50

Next, she uses a $5 off coupon. Thus, we want to subtract $5 from the price. 

Lets combine this all together!

24.50 = S*.50 - 5

Solve for S.

24.50 = S*.50 - 5
29.50 = S*.50
$59 = S

Thus, the original price of the sweater was $59.
