Carmen spent $88 which was 25% of the total she had. how much did she have?

352 will be your answer

Step-by-step explanation:

88 times 4 because 88 is 25 percent and 4 time 25 is 100 percent so just mmultiply 88 times 4 to get 100% of the money

25% is 1/4. So that means 88 is 1/4 of the total. We can multiply 88 times 4 to get $352. Hope this helps.

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
