Question

2x-(3*0.6x+2.7)

Answer 1

alright do you know how to distribute?

Answer 2

First simplify what is inside the parenthesis. Then distribute the negative, then combine like-terms.

Answer 3

Start with : (3 \(\cdot\)0.6x+27)

Answer 4

is is3*2.7+0.6x?

Answer 5

no you only multiply the 3 to the 0.6

Answer 6

What does that give you?

Answer 7

but i though you dont multipuly a number with a like term and a normal number.

Answer 8

if it was written 3(27 +0.6x) then you would multiply the 3 to both the 27 and 0.6x. In this case, we are only multiplying it with 0.6x

Answer 9

ok

Answer 10

So what does multiplying 3 to 0.6x?

Answer 11

1.8

Answer 12

Okay. So we can write our equation as

2x-(1.8x+2.7)

Answer 13

Now we distribute the negative to all values inside the parenthesis. What does end up being?

Answer 14

3.6x + 5.4

Answer 15

19.44

Answer 16

You should have gotten -1.8x -2.7

Answer 17

So now we will have :2x - 1.8x -2.7

Answer 18

2.5

Answer 19

or 0.2-2.7

Answer 20

Yes, don't forget your x's!

(2-1.8)x -2.7

= 0.2x -2.7 \(\checkmark\)

Answer 21

thank you

Answer 22
