Class rings are sold by a nearby jewelry store, which buys them for $60 each. The **amount **of **markup **is y=204.

Given that,

Class rings are sold by a nearby jewelry store, which buys them for $60 each. The ring has a name and date engraved on it, and the retailer **markup **it up by 340% before selling it.

We have to find the equation that can be used to find the **amount **of **markup **y.

So,

We can write the equation as

**Amount **of **markup**=340% of the purchases **amount**

Taking **amount **of the **markup **as y and purchases **amount **is $60.

y=340%×60

y=340/100×(60)

y=34×6

y=204

Therefore, The **amount **of **markup **is y=204.

there is a linear relationship between the distance that a car drives and the amount of gas left in the tank of the car. the value of r2 for this linear relationship is 98.01%. what is the value of r?

A **linear relationship** between the distance that a car drives and the amount of gas left in the tank of the car is **negative**, and the** **value** **of r is -0.99

A linear relationship between the distance that a car drives and the amount of gas left in the tank of the car are negative because when a car travels a distance, it **consumes** fuel, and so fuel decrease with distance

Calculating the value of r

Given, r^2=98.01%

r^2=0.9801

r=±√0.9801

r=±0.99

Since r should be negative, so we pick the negative value and reject the positive value

Answers for the chart left to right

(-2, 4 1/2) (-1, 4) (0, 3 1/2) (1, 3) (2, 2 1/2) (3, 2)

Step by step

First I put our equation into y intercept form

2y = -1x + 7

Divide both sides by 2 to isolate y

2/2 y = -1/2x + 7/2

y = -1/2x + 3 1/2

Now we fill in your chart

From this we see the y intercept is at 3 1/2, so at (0, 3 1/2) is our coordinate on the y axis.

Enter this on your chart at 0x.

From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0

3 1/2 + -1/2 = 3, (1, 3)

3 + -1/2 = 2 1/2 (2, 2 1/2)

2 1/2 + -1/2= 2 (3, 2)

Moving left from 0

3 1/2 - -1/2 = 4 (-1, 4)

4 - -1/2 = 4 1/2 (-2, 4 1/2)

Now you can graph your points

I did a graph for you as an example in the attachment

2y = -1x + 7

Divide both sides by 2 to isolate y

2/2 y = -1/2x + 7/2

y = -1/2x + 3 1/2

Now we fill in your chart

From this we see the y intercept is at 3 1/2, so at (0, 3 1/2) is our coordinate on the y axis.

Enter this on your chart at 0x.

From here, we see our slope or rate of change is - 1/2 for every x value. So moving to the right from 0

3 1/2 + -1/2 = 3, (1, 3)

3 + -1/2 = 2 1/2 (2, 2 1/2)

2 1/2 + -1/2= 2 (3, 2)

Moving left from 0

X=

Note: the answers have to be either integers or decimals

**Answer:**

x = 4 , x = 2.4

**Step-by-step explanation:**

[tex]\frac{4}{x-2}[/tex] + [tex]\frac{3}{x-3}[/tex] = 5

multiply through by (x - 2)(x - 3)

4(x - 3) + 3(x - 2) = 5(x - 2)(x - 3)

4x - 12 + 3x - 6 = 5(x² - 5x + 6)

7x - 18 = 5x² - 25x + 30 ( subtract 7x - 18 from both sides )

0 = 5x² - 32x + 48

consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 5 × 48 = 240 and sum = - 32

the factors are - 20 and - 12

use these factors to split the x- term

0 = 5x² - 20x - 12x + 48 ( factor the first/second and third/fourth terms )

0 = 5x(x - 4) - 12(x - 4) ← factor out (x - 4) from each term

0 = (x - 4)(5x - 12)

equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

5x - 12 = 0 ⇒ 5x = 12 ⇒ x = 2.4

2x+3x+4x=180 what’s x

[tex](2x + 3x + 4x) = 180 \\ 9x = 18 \\ \frac{9x}{9} = \frac{180}{9} \\ x = 20[/tex]

ATTACHED IS THE SOLUTION with the steps.

2x+3x+4x=180
