Here is my question: 2n + 4 = 4n + 1 - 2n
(keep in mid it's either an infinite solution, 0, or 1)

Answers

Answer:

0 solutions

Step-by-step explanation:

2n + 4 = 4n + 1 - 2n

                        ↑

first combine like terms (right side)

2n + 4 = 2n + 1

but this part you can tell that there's 0 solutions, because both sides have 2n/ same variable with same number.

No Solution.

Once you combine the like terms 4n-2n of the second equation you end up with

2n+4 = 2n+1.

There is no value of n that results in a true equation.

Maria had 4 full cement, blocks & one that was 5/9 the normal size, If each full block weight 3 8/9 pounds, What is the Weight blocks maria has? (20 POINTS!)

Answers

I have no idea I hope you find the awnser though

The total Weight blocks maria has is 15.2 pounds.

What is Fraction?

A fraction represents a part of a whole.

Given that Maria had 4 full cement, blocks & one that was 5/9 the normal size.

Each full block weight [tex]3\frac{8}{9}[/tex] pounds

We need to find the Weight blocks maria has

Let us convert the mixed faction to improper fraction

35/9 = [tex]3\frac{8}{9}[/tex]

As there are 4 full cement, blocks

So multiply 4 with  [tex]3\frac{8}{9}[/tex]

4×35/9

4×3.8

15.2

Hence,  the total Weight blocks maria has is 15.2 pounds.
