Answer 1

Answer:

2x - 10 = 10 - 3x

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Which represents the solution for the inequality -7x +42 < or equal to 28 ?

A. x is greater than or equal to -10
B. x is less than or equal to -10
C. x is less than or equal to 2
D. x is greater than or equal to 2

Answers

Answer:

The answer is D.

Step-by-step explanation:

If we plug in the first two answers (-10):

-7(-10) +42 < or equal to 28

Two negatives equal a positive so: 70+42=112 which is not less than or equal to 28.

So both A and B are not correct, because -10 results in a number GREATER than 28.

This means it has to be either C or D and both use the number +2, so we'll try +1 to solve for C, and +3 to solve for D.

For C: -7(1) +42 < or equal to 28

-7+42=35 which is NOT less than or equal to 28

For D: -7(3) +42 < or equal to 28

-21+42=21 which IS less than or equal to 28

Each number greater than 2 will give you a larger number being subtracted from 42, and that result will always be less than or equal to 28.

The answer is D x is greater than or equal to 2

3.75*640=2,400 (Carpet)

340/80=4.25
