Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50. If the sales tax rate is 8.25%, what will be the amount of sales tax on Cassie’s purchase?
$3.13
$2.97
$3.06
$2.89

Answers

The amount of sales tax is $2.97.

The tax for the shoes: 26.50*0.0825=2.18625

The tax for the shirt: 9.5*0.0825=0.78375

2.18625+0.78375=2.97

pls mark brainliest:))

Answer:

B. 2.97

Step-by-step explanation:

First, add 26.5 plus 9.5 to get the total of the purchase without tax. Then, create a proportion (8.25/100= x/36). multiply 8.25 by 36, and divide the product by 100 to get 2.97. Hope this helps!

A triangle has one side that measures x, and the other two sides each measure 4 inches less than x. The perimeter is 19 inches.

What is the measure of x?

5
3
9
2

Answers

Answer:

x=9

Step-by-step explanation:

x + x - 4 + x - 4 = 19

3x - 8 = 19

3x = 19 + 8

3x = 27

x = 9

Answer: x=9

Step-by-step explanation:

There are three sides 2 that are x-4 and 1 that is x. The equation would be

x+2(x-4)= 19 so you would simplify to get

X+2x-8=19 then 3x=27 then divide by three to get x=9

Two pools were being filled. Pool A was being filled 1/8 of a gallon in 1/12 of a minute, and pool B was being filled at 3/8 of a gallon in 1/9 of a minute. Which pool is being filled up faster?

−15x−40=23−8x
What does x =

Answers

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x  

Add 8x to both sides

-15x + 8x - 40 = 23

          -7x - 40 = 23

Add 40 to both sides

                - 7x = 23 + 40

                  -7x = 63

 Divide both sides by (-7)

            x = 63/-7

x = -9

Answer:

x = -9

Step-by-step explanation:

-15x - 40 = 23 - 8x

add 8x to both sides to bring -8x to the left side

-15x + 8x - 40 = 23

add 40 to both sides to bring -40 to the right side

-15x + 8x = 23 + 40

add the common terms

-7x = 63

for x to be alone divide -7 to both sides

x = -9
