Answer 1

Answer:

Step-by-step explanation:

answer no 3:

1] Factor out the common term 2.

2(3x+y) = -26

2] Divide both sides by 2.

3x+y= -26/2

3x+y = − 13

 

3]Subtract y from both sides.

3x = - 13-y

4] Divide both sides by 3.

x = -13-y/3

Part 2:-

Add 6y to both sides.

x=21+6y

x=21+6y

If y varies directly with x, write an equation for the direct variation. Then find each value,
if y = 6 when x =30, find y when x = 15

Answers

Just a guess Bc I’ve no idea what you’re talking abt, but 3. Would set 30/6 and 15/y cross multiply, solve for y and get y =3
I think 3, because 15 is half of 30 and 3 is half of 6. Hope this helps

MY WORK:

First, you would cut it up into different parts/shapes

(I cut it up into rectangles)

Then, you would find the area of each.

The bottom rectangle: 10 ( 5 times 2 )

The middle rectangle: 12 ( 6 times 2 )

The top rectangle: 8 ( 4 times 2 )

Lastly, you would add!

10 + 12 + 8 = 30

Therefore, the answer is...

30!

My apologies if this is wrong but I hope I helped a little bit!
