A customer bought a car and paid $1,080 in sales tax.The rate is 6%?

Ghella [55]

The price of car is $18000

Step-by-step explanation:

Given

Sales tax on car = $1080

Rate = 6%

Let x be the price of the car

We know that as the rate of sale tax is 6%, 6% of x is 1080

Using mathematical notation

0.06x = 1080

Dividing both sides by 0.06

$\frac{0.06x}{0.06} = \frac{1080}{0.06}\\\\x = 18000$

Hence,

The price of car is $18000

{15×115-(-3)}(4-4)÷3{5+(-3)×(-6)} simplify the expressions <br>

Lena [83]

Answer:

Step-by-step explanation:

Alright, so we all know that the order is { [ ( ) ] } right?

1. { }

2. [ ]

3. ( )

Those are the IMPORTANT orders!

So first, 15 x 155 is 2325, and - and - is a +.

The first part is 2328, ( 2325 + 3 ).

The second part is 4-4 ÷ 3, don't forget, PEMDAS!

Prentices

Exponents

Multiplication

Division

Addition

Subtraction

So no, you will not divide 4 and 3 first.

First, do 4 - 4 which is 0.

And then 0 ÷ 3 which is 0.

The third part is 3 { 5 + ( - 3 ) x ( - 6 ) }

The outside 3 means that we will multiply after we get the answers.

But first, -3 x -6 is 18 because - and - is +.

Now, 5 + 18 which is 23.

3 times 23 is 69!

The fourth part is really easy, just add them all up!

2328 x 0 + 69

And lastly, we know that the answer is 0.
