Answer 1
Answer: Subtract 8x from 13x to get 5x.
5x=10

Divide each term in the equation by 5.

Marcus can choose between a monthly salaryof $1,500 plus 5.5% of sales or $2,400 plus 3% of sales. He expects sales
between $5,000 and $10,000 a month. Which salary option should he
choose? Explain

Answers

Marcus should choose $2,400 plus 3% of sales. 

His salary is composed of a fixed salary and a variable salary.

Fixed Salary   +   Variable Salary  = Monthly Salary
2400                   150 (3% of 5k)    = 2350  - minimum salary he'll receive
2400                   300 (3% of 10k)  = 2700  - maximum salary he'll receive

VS

Fixed Salary    + Variable Salary  = Monthly Salary
1500                  275 (5.5% of 5k) = 1775 - minimum salary he'll receive
1500                  550 (5.5% of 10k) = 2,050 - maximum salary he'll receive

As you can see, despite the high percentage of sales offered, it is not a good option because the fixed salary is low as compared to the other option. Even the maximum salary he'll receive under the option $1500 is way lower than the minimum salary he'll receive under the option $2400.

What is 18x-9(x-1)=5(3x+3)

Answers

Answer:

-4

Step-by-step explanation:

18x - 9(x - 1) = 5(3x + 3)

Step 1: Distribute

18x - 9x - 9 = 15x + 15

Step 2: Combine like terms

9x - 9 = 15x + 15

Step 3: Solve by using opposites terms, try to get x on one side and the solution on the opposite side

9x - 9 = 15x + 15

-9x        -9x

-9 = 6x + 15

-15         -15

-24 = 6x

/6      /6

-4 = x

What total length of ribbon is needed to Line the two long sides of the hat?

Answers

Answer:

Total length of ribbon to line the long sides will be 22 in

Step-by-step explanation:

In the given figure of kite if we draw a line "h" vertically will form two right angle triangles.

Then by applying Pythagoras theorem in both the triangles.

h²= (3x + 5)² + (2x + 1)² ------(1)

h²= (5x + 1)² + 5² ------(2)

By equating both the equations

(3x + 5)² + (2x + 1)² = (5x + 1)² + 25

9x² + 25 + 30x + 4x² + 4x + 1 = 25x² + 10x + 1 + 25

13x² + 34x + 26 = 25x² + 10x + 26

13x² - 25x² + 34x - 10x + 26 - 26 = 0

- 12x² + 24x = 0

12x² - 24x = 0

x² - 2x = 0

x(x - 2) = 0

x = 2

Now we will put x = 2 in the measure of sides of the kite.

Side 1 = (3x + 5)

          = 3×2 + 5

          = 11

Side 2 = (5x + 1)

          = 5×2 + 1

          = 11

Side 3 = (2x + 1)

          = 2×2 + 1

          = 5

Therefore, Total length of ribbon to line the long sides will be = 11 + 11

= 22 in.

Your answer will be D-22.
