a little help anyone? plz put the answers so their obvious

Answers are in bold.

1) Carlo: 4x, Helen: $3.75

2) 4x + 3 = 2x + 3.75 + 2.75

4x + 3 = 2x + 6.5

4x - 2x + 3 = 2x - 2x + 6.5

2x + 3 = 6.5

2x + 3 - 3 = 6.5 - 3

2x = 3.5

2x/2 = 3.5/2

x = 1.75

3) The cost of each glue stick is $1.75

4) There are no solutions.

Step-by-step explanation:

1) First, we need to form our equation:

(4x + 3) = (2x + 3.75 + 2.75)

Now, we combine like terms:

4x + 3 = 2x + 6.5

Combine like terms again:

2x + 3 = 6.5

Subtract 3 from both sides:

2x + 3 - 3 = 6.5 - 3

Simplfy:

2x = 3.5

Divide 2 from both sides:

x = 1.75

Each glue stick costs $1.75

4) It is the same process, form equation, combine like terms, subtract from both sides, and divide if possible.

3(4x + 1) = 6(2x - 5)

12x + 3 = 12x - 30

3 = -30

3 does not equal -30, therefore there are no solutions.
