125% markup

Step-by-step explanation:

Hope this helps :)

The percentage markup the store has made is 125%.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, A shoe store paid the manufacturer $27.00 for a new pair of basketball shoes.

The store sells basketball shoes for $60.75.

So, Amount markup is $(60.75 - 27.00) = $33.75.

∴ The percentage markup is (33.75/27)×100%.

= 125%

Rewrite the second equation:

This is to make the calculation easier. There are other ways to do this as well.

3y = 3x - 6

Substitute that into the first equation:

Since they are the same thing (=), it is possible to replace 3y.

2x + (3x - 6) = 9

Solve the equation:

2x + 3x = 9 + 6

5x = 15

x = 3

Substitute x = 3 into the first equation:

2(3) + 3y = 9

6 + 3y = 9

3y = 3

y = 1

Answer: x = 3, y = 1

Answer:

weight of the kitten last year = 9 ounces

Step-by-step explanation:

Let

x = weight of the kitten last year

Weight of the kitten this year = 2 1/3 * x = 21

7/3*x = 21

7/3x = 21

x = 21 ÷ 7/3

x = 21 × 3/7

= 63/7

x = 9 ounces

weight of the kitten last year = 9 ounces

Answer:

b. x^4 + 4x^2 + 8x

Step-by-step explanation:

I took the test. Also the exponents need to be in descending order in order for the equation to be in standard form.

So b, starts with an exponent of 4, the decreased to just the x variable with an understood exponent.

Decreasing -> 4,2,(1)

Answer:

The slope of the equation is the final option listed: The slope is 7.

Step-by-step explanation:

In a y = mx + b equation, b represents the slope. So, whatever 'b' is, that's the slope. In this equation, we have y = 7x+2, so that means that the slope is 7. It also means that the y-intercept is 2. I'll attach a photo that helps!

Answer:

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form

Step-by-step explanation:

Use the point-slope form of a line to do this problem.

[tex]y - y_{1} = m(x - x_{1} )\\[/tex]

In your case [tex](x_{1} , y_{1} ) = (8, 4)[/tex]

So. y - 4 = 3/2 ( x - 8)  

multiply thru by 2

2y - 8 = 3(x - 8)

2y - 8 = 3x - 24

2y = 3x - 16

y = (3/2)x - 8    slope-intercept form

3x - 2y = 16      standard form

First degree polynomials means that the maximum power x is raised up to that does not have a coefficient 0 is 1. And here we have a term ax^2 which means it could not be a first degree polynomial if a has a positive or negative value. Thus, letter a in this case should be 0 in order for this to be a first degree polynomial of x.

Answer:

a = 18

Step-by-step explanation:

2(a-7)=a+4

Distribute 2 into left side: 2a -14 = a + 4

subtract a from both sides  2a-a-14 = a+4-a

Simplify: a  - 14 = 4

Add 14 to both sides: a - 14 + 14 = 4 +14

Simplify:   a = 18

If wanted, plug a into original to double check work:

plug in: 2 (18-7) = 18+4

do parenthesis first: 2 (11) = 18+4

do multiplication : 22 = 18+4

additions: 22 =22

a = 18 is correct.

Answer:

A=18

Step-by-step explanation:

2(a-7)=a+4

2a-14=a+4

add 14 to both sides

2a=a+18

subtract a from both sides

a=18

Total pounds of candy bought = 8.25

Candies that are red = 2.5

Candies that are blue = 3.75

Candies that are white willbthen be:

Total pounds bought - (Red + Blue)

= 8.25 - (2.5 + 3.75)

= 8.25 - 6.25

Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.

X=6

Step-by-step explanation:

(8x-4)+(3x+17)=(17x-23)

Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.

11x+13=17x-23

Now this is what the equation should look like after combining ur alike terms.

11x+13=17x-23

-11x. -11x.

now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.

13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.

36=6x and now u just divide the 36 by 6 and remember to always divide by the x

Now the answer is x=6
