For this case we must simplify the following expression:

-3 (10x + 4y) +6 (6x-2y)

We apply distributive property to the terms of the parenthesis, taking into account that:

- * - = \\- * + = -

So, we have:

-30x-12y + 36x-12y =

We add similar terms:

-30x-12y + 36x-12y =

Equal signs are added and the same sign is placed, while different signs are subtracted and the sign of the major is placed:

6x-24y

Answer:

6x - 24y

Explanation:

Expand -3(10x + 4y): -30x - 12y

= \bold{-30x-12y+6\left(6x-2y\right)}

Simplify \bold{-30x-12y+6\left(6x-2y\right): \ 6x-24y}

= 6x - 24y

1.Hannah walked the same number of miles each day for 5 days. Let m represent the total number of miles Hannah walked. Write a l
mamaluj [8]

1) Given m represent the total number of miles Hannah walked.

Let us assume Hannah walked x miles each day.

So total number of miles Hannah walked in 5 days is m=5x.

2)Given Jimmy brought 2 books per day and Peter brought 4 books per day.

If d is the number of days the book drive, total number of books they brought

        =total number books brought by Jimmy+ total number of books brought by Peter                                                                          

        = 2d+4d = 6d

3) Given that c represent cost of the clothes.

Then 30% discount = 0.3c

Hence cost of the clothes = c-0.3c = 0.7c

4) Given c represent the cost of their meal before tipping.

And tip is 15% of the cost.

Hence tip = 0.15c

Hence total bill = c+0.15c=1.15c

5) Given that Tommy had 40$ in his pocket.

And pair of pants cost 37$ with 10% sales tax.

Hence cost of pants including sales tax = 37+37*0.1 = 40.1$ >40$

Hence Tommy cannot afford the pants with 40$ in his pocket.

For following problems, we should group the like terms together and then simplify.

6) (x+8)+(3x-12) = (x+3x)+8-12 = 4x-4

7) 5x+7-(3x-4) = 5x+7-3x+4 = (5x-3x)+7+4 = 2x+11

8) (x-2)-(-4x+1)=x-2+4x-1 = (x+4x)-2-1 = 5x-3
