Answer:

4

Step-by-step explanation:

Proportionality between skein values

8:2=4:1

Proportionality between cost values

28:7=4:1

The variation(both the skein values and cost values) has the constant of 4 ie the 1st skein value × 4= the last skein value & the 1st cost value × 4=the last cost value

Kristin won 44 lollipops playing basketball at her school's game night. Later, she gave two to each of her friends. She only has
Colt1911 [192]
21 friends.



44 - 2x = 2, where x is the number of friends Kristin has.

Subtract 2 on each side.

42 - 2x = 0

Add 2x on each side.

42 = 2x

Divide by 2 on each side.

42 / 2 = x

21 = x

Kristin has 21 friends.

Solve for x<br><br> 2/7x = 6<br><br> (SHOW YOUR WORK)
castortr0y [4]

Answer:

The answer to your question is  x = 21

Step-by-step explanation:

Equation

                                       \frac{2}{7} x = 6

- Multiply both sides by 7

                                        \frac{(2)(7)x}{7} = 6(7)

- Simplify

                                        2x = 42

- Divide both sides by 2

                                         \frac{2x}{2} = \frac{42}{2}

- Simplify

                                         x = 21
