Felicia brought 5
9
of a gallon of water for the track team. She poured the same amount of water into 10 cups. Then she calculated how much water she poured into each cup.

Which expression would you use to find the amount of water in each cup?
10 times StartFraction 5 Over 9 EndFraction
10 divided by StartFraction 5 Over 9 EndFraction
StartFraction 5 Over 9 EndFraction divided by 10
StartFraction 5 Over 9 EndFraction times 10

The expression ÷ 10 can be used to find the amount of water in each cup.

Step-by-step explanation:

Step 1; Felicia brought of a gallon of water to give to the track team. So the total amount of water she brought is   gallons. So the options 10 ×   and         × 10 cannot be the answers as they are more than the total amount of water.

Step 2; So to find the amount of water in each cup, we divide the total amount of water by the number of cups. The number of cups is 10. So the water in each cup is   ÷ 10.

So the third option can be used to calculate the water she poured into a cup.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
