Answer:

A. 21, 16, 28

Step-by-step explanation:

1st side = x

2nd side = x-5

3rd side = x+7

x+x-5+x+7 = 65

3x + 7 - 5 = 65

3x + 2 = 65

3x = 65-2

3x = 63

63/3 = 21

x = 21

therefore, the sides are 21, 16, and 28

Hillary needs a few new items for the start of softball season. She found some great sales! Help her find out the price she will

kolezko [41]

Answer:Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats

Step-by-step explanation:

Step 1

A percentage off of a price of an item is the amount that can be saved from purchasing that item, it can also be referred as a discount given on an item purchase.

Step 2 --- Calculation

Actual Price of Softball glove= $50

Discount= 50 x 30/100 = $15.00

Price to pay= $50 - $15.00 = $35.00

Actual Price of soft ball bat= $50

Discount= 50 x 60/100 = $30.00

Price to pay= $50 - $30.00 = $20.00

Actual Price of cleats= $50

Discount= 50 x 20/100 = $10.00

Price to pay= $50 - $10.00 = $40.00

Therefore, Hillary will pay $35.00 for softball glove, $20.00 for soft ball bat and $40.00 for cleats
