Answer: 8(n-2) ≥ 75


n = number of scarves he needs to sell

1 scarf = $8
n scarves= 8n

He is giving away 2 free, this means that he made n scarves but sell (n - 2) scarves.
He wants to earn at least $75

8(n-2) ≥ 75

---------------------------------------------
Answer: 8(n-2) ≥ 75

when 1760 is divided into 14 equal parts the remainder is 10. what is a correct way to write the quotient ​
Ivanshal [37]

Answer:

125 10/14

Step-by-step explanation:

1,760/14 = 125 r10

- 125 x 14 + 10 = 1,760

You turn the remainder into a fraction using whatever number you divided the main number by. In this case that would be 14.

6-8x=7x-10x-24 solve for x
lana66690 [7]

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6
