Your problem did not have an operator between the x and 1 so I did it as subtraction and addition. There was no answer choice -3 so D x=-9 is the answer

kiruha [24]

Answer:

The total purchase is $ 1213.13 .

Step-by-step explanation:

As given

You buy some living room furniture.

The coffee table costs $189.99.

The loveseat costs $249.95.

The sofa costs $493.68, and 2 chairs cost $98.75 each.

Total cost of the furniture =   coffee table costs  +  loveseat costs +  sofa costs  +  2 chairs cost

Put the value in above

Total cost of the furniture =  $189.99 + $249.95 +  $493.68 + 2 × $98.75

Total cost of the furniture =  $189.99 + $249.95 +  $493.68 + $197.5

Total cost of the furniture = $1131.12

As Sales tax is 7.25% .

7.25% is written in the decimal form.

= \frac{7.25}{100}

= 0.0725

Sales tax price = 0.0725 × $1131.12

                        = $ 82.01 (Approx)

Total purchase = Total cost of the furniture + Sales tax price

                         = $1131.12 +  $ 82.01

                         = $ 1213.13

Therefore the total purchase is $ 1213.13 .

Divided 80 by my number, and then added 13. The result was 93. What was my number?
igor_vitrenko [27]

The number is 6400.

We have given that,

divided 80 by my number, and then added 13.

<h3>What is the expression?</h3>

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Suppose the number is x

\frac{x}{80}+13=93

Subtract  13  from both sides

\frac{x}{80}+13-13=93-13

\frac{x}{80}=80

Multiply both sides by 80

\\\frac{80x}{80}=80\cdot \:80

x=6400

Therefore the number is 6400.
