Step-by-step explanation:

The number of times you write 2 as a factor of 552 is 3 times.

Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

The given numerical expression is 23·24.

Here, equivalent expression is 552

Factor of 552 is

2×2×2×3×23

Therefore, the number of times you write 2 as a factor of 552 is 3 times.

$90

Step-by-step explanation:

Given parameters:

    Selling price of belt = $120

     Percentage discount = 25%

Unknown:

Discount = ?

Sale price of the dress  = ?

Solution:

Discount is a reduction in the price of a commodity.

     Discount  = percentage discount x selling price of belt

 Input the parameters and solve;

I.    Discount  = [tex]\frac{25}{100}[/tex] x 120 = $30

II. Sale price of the dress;

               = selling price - discount amount

                 = $120 - $30

                  = $90

The width of the rectangle is 8in

Step-by-step explanation:

Given parameters:

     Perimeter  = 44in

     Length  = 14in

Unknown:

Width of the rectangle  = ?

Solution:

The parameters given can be used to determine the unknown dimension;

        Perimeter of a rectangle  = 2 (L + W)

L is the length

W is the width

   Input the parameters and solve;

         44  = 2 (14 + W)

         44  = 28 + 2W

          2W  = 16

            W = 8in

The width of the rectangle is 8in

Answer:

Okay this might be slightly confusing but I'll try to make it simple. x = -10

Step-by-step explanation:

-4 ( 3x - 7 ) + 5x = -2x + 8 1. get rid of parenthesis first. -4 times 3x = -12x and -4 times -7 is 28

-12x + 28 + 5x = -2x + 8 2. Combine any like terms on each side of the equation. -7x + 28 = -2x + 8 3. Get rid of the smallest x value by adding to both sides -7x

+7x +7x

28 = -2x + 8 4. subtract 8 from both sides to get rid of it. (you wanna get x alone)

-8 -8

20 = -2x 5. Divide both sides by -2 to get 1x (which is x)

/-2 /-2

x = -10

Ok:

Step-by-step explanation:

I see that you set up 90 miles = 60 mph * t, where you found out that t = 1.5. What what you needed to do was set 180 miles = 45 mph * t. This is because it is 45 mph for the whole trip. Then, you find that t = 4 hours. That that means that he spent 2.5 hours driving back. Then, we can do d=vt and find 90/2.5 as the speed he went home at. Which comes out to be 36 mph.

Answer:

75 = 25 x 3.

Step-by-step explanation:

this is the answer the picture above

Answer:

it is c $10.80

The sales tax on clothing that costs $180 is $10.80 with 6% sales tax. The correct answer is option c.

Given that:

The cost of cloth is $180.

Sales tax is 6%.

To calculate the sales tax on clothing that costs $180 at a rate of 6%, follow these steps:

Convert the sales tax rate to a decimal: 6% = 6/100 = 0.06

Sales tax can be calculated by using the formula given below:

Sales tax = Cost of clothing × Tax rate

Multiply the clothing cost by the sales tax rate to find the sales tax amount:

Sales tax = Cost of clothing × Tax rate

Sales tax = $180 × 0.06 = $10.80

Hence, the required value is $10.80. The correct answer is option c.
