how many. toy cabins can lvan make?
how many sticks will be left?

11 toy cabins

12 craft sticks will be left.

Step-by-step explanation:

To make each toy cabin, Ivan uses 30 craft sticks.

So, Ivan uses the craft sticks in multiple of 30 to make any number of toy cabin.

If he has a box of 342 craft sticks, then he will use 330 craft sticks to make toy cabin.  

{Since 330 is the multiple of 30 that is closest to 342}

Therefore, there will be (342 - 330) = 12 craft sticks left to use. (Answer)

the line of

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
