x - 3y = 4

3(3y + 4) + 2y = -21
3(-3y + 4) + 2y = -21

The numbers represented by variables w and y on the number line are integers.
mixas84 [53]

<u>Option A)</u> when y=6 and w= 2, <u>Option B)</u> when y=4 and w=-1 are the TWO correct choices.

Step-by-step explanation:

The given inequality is w<x<y and x>2.

<u>step 1</u>: let us <u>assume that x=3</u>, since it is given that x>2.

<u>step 2</u>: substitute the value of x=3 and each options in the inequality

<u>step 3</u>: option A) w=2, y=6. Then w<x<y = 2<3<6 (the condition satisfies).

            option B) w= -1, y=4. Then w<x<y = -1<3<4 (the condition satisfies).

            option C) w= 0, y=2. then w<x<y ≠ 0<2<2 (does not satisfies).

            option D) w= -2, y=0. then w<x<y ≠ -2<2<0 (does not satisfies).

            option E) w= -4, y= -1. then w<x<y ≠ -4<2<-1 (does not satisfies).

elixir [45]
The ratio is 20:35 or 20 to 35 and also 20/35, there are multiple ways to write it. My personal favorite is the first one but it depends on what your teacher wants!
