Masha bought red, green, and yellow balloons for a party. she bought 40 red balloons. the number of green balloons masha bought is 3/5 of the number of red balloons. the number of green balloons is also 2/3 of the number of yellow baloons. while being inflated, 1/20 of the red balloons, 1/12 of the green balloons, and 1/36 of the yellow balloons popped. the remaining balloons were used as party decorations. what part of all the balloons masha purcashed decorate the party? i need help thank u <3

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
