2/3 (x – 7)= -2 i know x=4 but i need a good show of work for teacher worth 22 points make it worth it

Dafna1 [17]

Step-by-step explanation:

⅔ (x – 7) = -2

Let's start by getting rid of the fraction. Multiply both sides by 3.

2 (x – 7) = -6

Distribute the 2:

2x – 14 = -6

Add 14 to both sides:

2x = 8

Divide both sides by 2:

x = 4

-(b-5). Use the distributive property to write the expression as an equivalent algebraic expression

Dvinal [7]

Answer:

An equivalent algebraic expression of -(b-5) using distributive property is

-b+5

Step-by-step explanation:

We need to use distributive property to solve the expression -(b-5)

The distributive property states that $a(b+c)=ab+ac$

Using distributive property to solve the expression -(b-5)

$-(b-5)=-(b)-1(-5)\\=-b+5$

So, an equivalent algebraic expression of -(b-5) using distributive property is

-b+5

What algebraic expression must be added to the sum of 3x2 +4x+8 and 2x2−6x+3 to give 9x2−2x−5 as the result?

Gnom [1K]

4x² - 16 is the algebraic expression that must be added to get the result as 9x²- 2x - 5.

Step-by-step explanation:

The question is asked for the algebraic expression must be added to the sum of 3x²+4x+8 and 2x2−6x+3 to give 9x²- 2x - 5 as the result.

Therefore,

The first step is to find of sum of 3x²+4x+8 and 2x²-6x+3.

To find the sum :

3x²+4x+8

2x²-6x+3

5x²-2x+11

The sum is 5x²-2x+11.

Now, the second step is to subtract 5x²-2x+11 from the result 9x²- 2x - 5.

9x²- 2x - 5

- (5x²-2x+11)

4x² -16

Thus, 4x²-16 is the algebraic expression that must be added with 5x²-2x+11 to get a result of 9x²- 2x - 5.
