Mya bought 6 slices of bread for $2.40 at her local grocery store. How much would a package with 10 slices cost at the price
per slice?

$4.00

Step-by-step explanation:

Find how much it would cost for one slice of bread by dividing 2.40 by 6 to get .4.

So .40 cents is for 1 slice of bread. If you got 10 slices of bread (multiply 10 by .4) you would get 4.

So it costs 4 dollars for 10 slices of bread.

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
