Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items, including tax?
$127.46

$92.81

$82.27

$59.91

Answers

Answer:92.81

Step-by-step explanation:

Answer:

$82.27

Step-by-step explanation:

First, figure out how much it would be without tax.

(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25

Then, multiply this number by your tax rate.

77.25*6.5 = 5.02

Lastly, add your original total with this tax amount for your answer.

77.25+5.02= 82.27

An electrician needs 3 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 3/4 of a roll of wire?

Answers

Answer:

He can wire

[tex] \frac{1}{4} [/tex]

of a room with 3/4 of a roll of wire.

Step-by-step explanation:

We can solve by using proportions.

Let's set it up.

[tex] \frac{3 \: rolls}{1 \: room} = \frac{ \frac{3}{4} \: of \: a \: roll}{x} [/tex]

We are now going to cross multiply. By cross-multiplting, you would get:

[tex] \frac{3}{4} = 3x[/tex]

You are now going to divide both numbers by 3 in order to get the x by itself.

[tex] \frac{ \frac{3}{4} }{3} = \frac{3x}{3} [/tex]

By dividing, you get:

[tex] \frac{1}{4} = x[/tex]

Therefore, the answer is 1/4.

The number of rooms he can wire with 3/4 of a roll of wire is 1/4.

What are proportions?

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

Given that, an electrician needs 3 rolls of electrical wire to wire each room in a house.

Let the number of rooms he can wire with 3/4 of a roll of wire be x.

Now, the proportion is

[tex]\frac{3}{1}=\frac{\frac{3}{4} }{x}[/tex]

3x=3/4

x=1/4

Therefor, number of rooms he can wire is 1/4.

−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
