Expand and simplify

6(2x - 3) - 2(2x + 1)

8x - 20

Step-by-step explanation:

6(2x - 3) - 2(2x + 1)

Distribute

6(2x) -6( 3) - 2(2x) -2( 1)

12x -18 -4x -2

Combine like terms

12x -4x    -18 -2

8x-20

8x - 20

Explanation: To simplify the problem you see here, we are going to use both the distributive property and combining like terms.

But before we do anything, we need to change

these minus signs to plus negatives.

Now we can distribute the 6 through the first set of parentheses

and the -2 through the second set of parentheses.  

That gives us 6(2x) or 12x + 6(-3) or -18 + -2(2x)

which is + -4x + -2(1) which is + -2.

Now we can combine like terms.

12x + -4x is 8x and -18 + -2 is -20.

So 8x - 20 is our final answer.

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
