Answer: x = 18

Step-by-step explanation:

First, since both angles shown are equal to each other, you can immediately set your equation.

5x + 5 = 95

Next, move 5 to the opposite side of the equation to isolate your x value (5x). This step is simply subtracting the hanging 5.

5x + 5 (-5) = 95 (-5)

5x = 90

Finally, you need to divide both sides of the equation by 5 (the 5 next to the x) to *fully* isolate the x value.

5x / 5 = 90 / 5

x = 18

final answer: x = 18

Hopefully this helps with the remainder of your lesson! :)

Classify a triangle with angle measures of 63 degrees and 27 degrees.

Maksim231197 [3]

Answer:

right

Step-by-step explanation:

The sum of all three angle measures in a triangle will always equal 180 degrees. So, if you subtract 63 and 27 from 180 you will have your third angle measure, which is 90.

So now your 3 measures are 63, 27, and 90. Since one of the angles is a 90-degree angle, the triangle must be a right angle because a right angle has a measure of 90 degrees.

I hope this helps!

Which expression correctly represents twice of the sum of four and a number

tino4ka555 [31]

Let "a number" be represented with the variable x.

Solve the expression by breaking it apart:

"...the sum of four and a number": (x + 4)

"twice of...": 2(

"Twice of the sum of four and a number": 2(x + 4)

2(x + 4) is your answer.
