2 + 3w < -1 < 3w + 5       |subtract 3w from all sides

2 < -1 - 3w < 5       |add 1 to all sides

3 < -3w < 6        |change the signs

-3 > 3w > -6      |divide both sides by 3

-1 > w > -2 → -2 < w < -1 → w ∈ (-2, -1)

WILL MARK BRAINLIEST IF ITS RIGHT !!
Furkat [3]

Answer:

Around 0.22

<u>FIRST THOUGH, I FEEL LIKE 90 MIGHT HAVE MEANT TO BEEN 0.9, SO IF SO SUBSTITUTE THE 90 BELOW FOR 0.9!</u>

<u></u>

Step-by-step explanation:

Okay, so first.

Company A will be 50 a day plus 0.4 a mile

Company B will be 30 a day plus 90 per mile

We can write an equation like this:

50 + 0.4m = 30 + 90m

m = miles they are the same

Then we solve for m.

50 + 0.4m = 30 + 90m

     - 0.4m            - 0.4m

50 = 30 + 89.6m

- 30    - 30

20 = 89.6m

Divide both sides by 89.6

Around 0.22!

Dafna1 [17]

Answer:

Take the ratio

A    B    C      D      Total

3     6     8    4         21            (3+6+8+4 = 21)

B gets 6 out of every 21 items

Take that fraction times the total items

6/21 * 7434 = 2124

D gets 4 out of every 21 items
