Answer:

x=7

Step-by-step explanation:

Step 1: Simplify

20x-8=18x+6

Step 2: Inverse

We will move variables with variables and numbers with numbers.

(Subtract 18x from both sides)

2x-8=6

(Add 8 on both sides)

2x=14

Step 3: Solve

(Divide both sides by 2)

x=7

Olin [163]

Answer:

  • C. 3.0

Step-by-step explanation:

<u>Lets calculate the points:</u>

  • Art - 2 hrs - B (3)                ⇒ 2*3 = 6 points
  • History - 3 hrs - A (4)         ⇒ 3*4 = 12 points
  • Science - 4 hrs - C (2)       ⇒ 4*2 = 8 points
  • Math - 3 hrs - B (3)            ⇒ 3*3 = 9 points
  • Lab - 1 hr - A (4)                 ⇒ 1*4 = 4 points

<u>Totals</u>

  • Total hours = 13            
  • Total points = 39

<u>GPA = total points/ total hours</u>

  • GPA = 39/13 = 3.0

Correct option is C

Which number line represents the solutions to \x – 5) = 1?
Aneli [31]

Answer:

Second number line represents the [X-5]=1.

Step-by-step explanation:

Given : [X-5]=1 .

To find : Which number line represents the solutions to [X-5]=1.

Solution : We have given that [X-5]=1.

We can se the value x-5 is inside the modulus it may be positive or negative.

So, we will do it by both cases.

1) (x - 5) = 1

On adding by 5 both sides.

x = 1+5 = 6

x = 6.

2) if -(x-5) = 1

remove parenthesis

-x +5 = 1

On subtracting by 5 both side

-x = -4

On dividing by -1 both side

x = 4.

So , x = 4, 6.

Therefore , the second number line represents the [X-5]=1.

Find the sum of the measures of the interior angles of the figure.
Free_Kalibri [48]

Answer:

\huge\boxed{\sf  900}

Step-by-step explanation:

Sides of the figure = n = 7

<h3><u>Formula for measuring the interior angles of a polygon:</u></h3>

(n - 2)×180

Where n is the number of sides in the polygon

So,

<h3><u>Measure of interior angles in the figure:</u></h3>

= (n - 2) × 180

= (7 - 2) × 180

= 5 × 180

= 900
