The total is 90°. Set the equation

8x - 6 + 80 = 90

Simplify. Combine like terms

8x + 74 = 90

Isolate the x. Do the opposite of PEMDAS. What you do to one side, you do to the other

8x + 74 (-74) = 90 (-74)

8x = 16

8x/8 = 16/8

x = 2

2 is your answer for x

hope this helps

You take (8x - 6) then add 80 =90 then solve for x
8x-6+80 =90
x= 2

Answer:

Four less than an unknown value E) $y-4$

Quotient of a variable and four B) $\frac{z}{4}$

Some number to the power of four A) $a^4$

Four times an unknown value D) $4x$

Four more than some number C) $b+4$

Step-by-step explanation:

Let's analyze each statement separately:

- Four less than an unknown value --> this means that we have to subtract 4 to an unknown value. Calling $y$ the unknown value, it means we have to write

$y-4$

- Quotient of a variable and four --> this means we have to divide a variable by 4. Calling $z$ the unknown variabl, it means we have to write

$\frac{z}{4}$

- Some number to the power of four --> this means that we have to write the power of a number, in the form $a^m$ , where m in this case is equal to 4. Calling $a$ the unknown number, it means we have to write
