The table shows the price of packages of markers at a store. Each package sells for the same price. What is the price of 11 packages of markers?

$55

Step-by-step explanation:

2 of them would be for 10 dollars so if i divided 10 by 2 i would get 5. Then i would add 5 to the 50 dollars for the 10 packages. Which would result in the price being 55 dollars for 11 packs.

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
