Answer:

x-y=-2 2/3

Step-by-step explanation:

You can't have the exact value of x and y, so we have to iscolate the variables, which means getting rid of the three. You have to divide to both sides three.

(3x-y)/3=8/3, x-y=8/3 then you can simplify into mixed number, which is 2 2/3.

x-y=2 2/3. Hope it helped!

Which ordered pair is in the solution set of 6x + 4y ≤ −2?

Nutka1998 [239]

Answer:

x≤ −2/3y + −1/3

Step-by-step explanation:

because...

Step 1: Add -4y to both sides.

6x + 4y + −4y ≤ −2+−4y

6x ≤ −4y −2

Step 2: Divide both sides by 6.

6x/6 ≤ $\frac{-4y-2}{6}$

x ≤ −2/3y + −1/3

Therefor, the answer is x≤ −2/3y + −1/3

* Hopefully this helps:) Mark me the brainliest:)!!

Jacob went on a fishing trip. This year he caught 30 fish, which is six more than twice the number he caught last year. How many

NARA [144]

Answer:

12 fish

Step-by-step explanation:

You need to work this problem backwards. If he caught 30 fish, which was six more than twice the number he caught last year, you would start by subtracting six, leaving you with 24. Then you'd have to divide by 2, because it was twice plus six as many fish, which would give you 12 fish.

$\frac{30-6}{2}$ = x
