Answer:

2r

Step-by-step explanation:

r+3r_=6r

The left side would have to equal 6r

right now it is 4r

by adding 2r it would equal 6r making the equation true.

Hope this helps :)

Answer:

2r

Step-by-step explanation:

r+3r+_=6r

Let's simplify this first.  Subtract (r + 3r), or 4r, from both sides, obtaining

0 + _ = 2r

Then the quantity 2r, when placed in the blank, makes the equation true.

25% is 1 over 4 and that gives us divide by 4
So what you want to do here is divide 340 by 4 which gives us £/$85
You save around 85 if I’m correct please tell me if I’m wrong :)

Answer:

I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

201 inches.

Step-by-step explanation:

They use the expression s^3 to find the volume of plastic to make each cube. Luis says that if s=8, then the volume is 24 cubic mm. I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

#3

Part A

Blue: 3ft - 36in

Red: 60in - 5ft

Yellow: 2.5ft - 30in

Green: 12ft - 144in

Purple: 240in - 20ft

Part B

1 foot = 12 inches

16.75ft = 201in

I'm not sure how to do the expression

but if 1 foot = 12 inches, and you substitute 16.75 for a foot, then you have 201 inches.
