Which expression is equivalent to the expression shown?
4(-9 + (-3) + 8)

A
4(12 + 8)

B
4(-9) + 4(3 + 8)

C
4(1) + 4(-3)

D
4(-9) + 4(5)

Answers

Answer 1
The answer would be D.
Answer 2

The equivalent expression is 4(-9)+4(5), so option D is correct.

Equivalent expression:

Important information:

The given expression is [tex]4(-9+(-3)+8)[/tex].

The given expression can be written as:

[tex]=4(-9+(-3+8))[/tex]

[tex]=4(-9+5)[/tex]

[tex]=4(-9)+4(5)[/tex]

So, option D is correct.

The value of the given expression is:

[tex]4(-9+(-3)+8)=4(-4)[/tex]

[tex]4(-9+(-3)+8)=-16[/tex]

The value of other expressions are:

[tex]4(12+8)=80\neq -16[/tex]

[tex]4(-9)+4(3+8)=8\neq -16[/tex]

[tex]4(1)+4(-3)=-8\neq -16[/tex]

[tex]4(-9)+4(5)=-16[/tex]

It means options A, B and C are incorrect.

Therefore, the equivalent expression is 4(-9)+4(5), so option D is correct.

Okay so, $16.80 - $6.30= $10.50


So the answer is $10.50
So, the total cost is 16.80. The bead cost 6.30, so you need to subtract. 16.80 - 6.30 is 10.50. To figure out how much EACH pendant cost, you divide your answer (10.50) by 3 because there are 3 pendants. 10.50 divided by 3 is 3.50. Each pendant cost $3.50.

Step by Step: Solve:
3x + 2 ( 2x + 9 ) = 4

Answers

Answer:

3x + 2 (2x + 9) = 4

3x + 4x + 18 = 4

7x + 18 = 4

7x = -14

x = -2

Step-by-step explanation:

i think it should be -2. if im wrong sorry

3x+2 (2x+9) = 4

Take care of the parenthesis to get the following

3x + 4x + 18 = 4

Add the X values

7x + 18 = 4

Take 18 from both sides so it looks like this

7x = 4 - 18

From this you’ll get this

7x = -14

Divide both sides by 7

x = -14 / 7

Simplify

X = 7 * - 2 / 7

Simplify

X = -2
