Sara is buying items at a store. her total comes to $44.97. she uses all of the money that is still on a gift card to pay for part of the total. she pays the remaining $34.17 with cash. which percentage best describes the part of the total that sara paid for with the gift card

The answer is approximately 24%.

Step-by-step explanation:

The total value of items Sara bought = $44.97

Amount given in cash = $34.17

So, amount given in gift cards is = dollars

The percentage that best describes the part of the total that Sara paid for with the gift card with respect to total amount is =

≈ 24%

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

ratio is 2 : 9

the answer is three

13.5 : 3
