ill give the brainliest to the first one to answer IF CORRECT CUZ IMMA CHECK IT

#3:

8x+56=80

2x=6

x=3

#4

Fabian can make 3 batches of soup

Step-by-step explanation:

Equations

We'll use some algebra rules to set, simplify, and solve equations. LEt's start with question #3

We have the equation

From that expression, we'll try to find out which other(s) are equivalent. If we operate the fraction by the parentheses, we have

This expression eliminates the second alternative. If we had multiplied all the equation by 4 instead of performing the product:

This is equivalent to the first option. It's correct and should be checked out. Taking from this equation

If we subtract 2x, we have

This is different from the first option in the second row. It should not be checked out

Solving for x

This is equivalent to the last option. Finally,  

which is equal to the 3rd option, first row. To summarize, all the equations equivalent to the first given are

8x+56=80

2x=6

x=3

Question #4

From the 10 pounds of tomatoes Fabian harvested, he sets aside 2.8 pounds to make spaguetti sauce. This leaves him with (10 - 2.8) pounds of tomatoes to make x batches of soup, each one of which needs 2 2/5 pounds of tomatoes. The equation to solve is

Solving for x

Fabian can make 3 batches of soup

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
