Answer:

-6n + 8

Step-by-step explanation:

(-8n + 11) + (2n - 3)

First let's look at the expressions within the parentheses.

-8n + 11 ⇒ This expression is fully simplified because you cannot add different variables together.

2n - 3 ⇒ This expression is fully simplified because you cannot subtract different variables together.

Since we are adding these expressions, we can take away the parentheses.

-8n + 11 + 2n - 3

Now, let's rearrange the term so the like terms are next to each other.

-8n + 2n + 11 - 3

Simplify the variable.

-6n + 11 - 3

Simplify the constants.

-6n + 8

This is your simplified expression.

Hope this helps!

Solve for x. one fifth times the absolute value of the quantity x minus 4 end quantity minus 3 equals 6 A. x= -19 and x =-11 b.
Firdavs [7]

The value of x in the given expression can be either -41 or 45. The correct option is B.

<h3>What is Absolute Value?</h3>

An absolute value of |x| {modulus of x} is the value of a real number x, the value we get is always a non-negative number, for example, |-5| will give 5, and also, |5| will give 5 as well.

Given the modulus function (1/5)|x - 4| - 3 = 6. Now, there will be two cases of this because the value of x can be either negative, x<0 or it can positive, x>0. Therefore, the given modulus function can be solved as shown below.

  • When x>0,

(1/5)(x-4) - 3 = 6

(x/5) - (4/5) - 3 = 6

(x - 4 - 15)/5 = 6

x - 4 -15 = 30

x = 30 + 15 + 4

x = 45

  • When x<0

(1/5)(-x+4) - 3 = 6

(-x/5) + (4/5) - 3 = 6

(- x + 4 - 15)/5 = 6

- x + 4 -15 = 30

-x = 30 + 15 - 4

-x = 41

x = -41

Hence, the value of x in the given expression can be either -41 or 45.
