You must distribute first so -2•2x=-4xand -2•8=-16
So expanded form is 8.5x•(-2•2x)+(-2•8)

Answer:

\frac{9x}{2} - 16

Step-by-step explanation:

8.5x - 2(2x + 8)

Use the distributive property to multiply −2 by 2x+8.

8.5x - 4x - 16

Combine 8.5x and −4x to get 4.5x.

4.5x - 16

= \frac{9x}{2} - 16

Half the marbles in a bag are red, 1/6 of the marbles are blue, and the remaining 8 marbles are white how many total marbles are
Gemiola [76]

Hey there! I'm happy to help!

Let's represent the total number of marbles with the variable t. We have the following information.

1/2t+1/6t+8=t (1/2 of total are red, 1/6 of total are blue, 8 are white, add them up to get total)

Now, we solve for t.

1/2t+1/6t+8=t

We combine like terms.

2/3t+8=t

We subtract t from both sides.

-1/3t+8=0

We subtract 8 from both sides.

-1/3t=-8

We divide both sides by -1/3.

t=24

Therefore, there ae 24 total marbles in the bag.

Have a wonderful day! :D

y = k/x

8 = k/3

k = 24

sub back in

y = 24/x

y = 24/8
