an equation is shown below:

5(2x - 8) + 15 = -15

write the steps you will use to solve the equation and explain each step. (5 points)

Your answer is x = 1

Step-by-step explanation:

First start by distributing 5 to everything in the parenthesis.

5 * 2x = 10x

5 * -8 = -40

What you're left with is 10x - 40 + 15 = -15

Next subtract 15 from both sides.

10x - 40 + 15 - 15

The 15's will cancel each other out on the left side.

-15 - 15 = -30

What you're left with is 10x - 40 = -30

Next add 40 to both sides.

10x - 40 + 40

The 40's will cancel each other out on the left side

-30 + 40 = 10

What you're left with is 10x = 10

Divide both sides by 10 to get x by itself.

10x / 10 = x

10 / 10 = 1

What you're left with is x = 1

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
