Please someone help me and explain this question to me (the last question starting with a straw)
Anastasy [175]

Each straw is  4-1/8 inches long.
You have one gigantic piece of straw material, 123-3/4 inches long.
How many straws can you cut it up to make ?

 ===>                    (123-3/4)  divided by  (4-1/8)            straws.

Each one costs  $0.015  to make.
So, once you find the number of short straws you have,
multiply

===>                 (the number of short straws) x ($0.015) .

That'll tell you how much it costs to make all of them. 


Now you know how to do it on your own.
If you don't get  30 straws  and  $0.45 , please try again.

**WILL GIVE THE BRAINLIEST! & LIKE**
Tamiku [17]
1) combine like terms (k)
0 = 7k
k = 0/7 = 0
zero divided by any numbers will be zero

2) combine the like terms (the constant of -4 + 1)
9 = 6x - 3
add 3 to both sides
12 = 6x
x=2

3) -3+3=0
-4=v

4) 4+3=7
8=k+7
k=1

5)x-5x = -4x
16= -4x
x = -4
