Charmichael bought 9 tickets to attend a spaghetti supper fundraiser at her school. the equation 9x=58.50 can be used to find x the cost of each ticket in dollars which equation represents the cost of each ticket

6.5

Step-by-step explanation:

9x=58.50

This equation is telling us that she bought 9 tickets at x cost each and the total was 58.50

Simplify the equation to solve for x. Divide by 9 on both sides.

⁹ˣ/₉ = ⁵⁸·⁵⁰/⁹

x=6.5

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

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
