PLEASE HELP 100 POINTS GUARANTEED! PLEASE PUT THE ANSWER IN AN ALGEBRAIC EXPRESSION!!! ANSWER ALL AND YOU WILL RECEIVE BRAINLIEST 1. Negative one plus double a number totals nine.
2. Four equals the difference of eight and a number and the result is divided by four.
3. The difference of half of a number and three is equivalent to negative five.

plss mark me brainliest I know this answer I will tell you in comment

Step-by-step explanation:

1.

-1 + 2x = 9

to get the solution

2x = 10

x = 5

2.

4 = 8 - x

x = 8 - 4 = 4

x/4 = 1

we could also write this

4 = 8 - x | /4

1 = 2 - x/4

x/4 = 1

x = 4

3.

x/2 - 3 = -5

to solve

x/2 = -2

x = -4

a.) list the factors of 40.

1/2/4/5/8/10/20/40

b.) list the factors of 40 that represent the number of cans that could be on each shelf.

5

c.) how many different arrangements of cans are possible?

just one because if you put more on one shelf you will go way over 40 and the cabinet will probably break.

d.) what are the possible arrangements of the cans?

put 5 cans on each self to reach 40 cans in total.

e.) which arrangement uses all the shelves?

5 because you can put 5 cans on each shelf, and since there are 8 shelfs you are equally going to get 40 cans.
