QUICK PLSS 1. Jabo orders a meal that cost $20.00. a. If the tax rate is 7.5%, how much will the sales tax be on Jabo's meal? $

b. Jabo also wants to leave a 20% tip for the server? What does he pay the server? $

c. What does he pay in all? $

$25.80

Step-by-step explanation:

Find the cost of the meal with the sales tax:

20 x 0.075 = 1.5

Add the sales tax to the total

20 + 1.5 = 21.50

Find the tip:

21.5 x 0.2 = 4.3

Add the tip to the total cost so far:

21.50 + 4.30 = 25.80

the correct answer is 1: 2

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
