Answer:

x=16

Step-by-step explanation:

the angle would be 1/2 of the arc so here's the steps

(2)7x+16=18x-32

14x+32=18x-32

    +32        +32

14x+64=18x

-14x .     -14x

64=4x

64/4=4x/4

x=16

Answer:

The numerical expression is simplified into 8.

Step-by-step explanation:

You have to use the P.E.M.D.A.S. formula.

16-8[(3+6)÷9]

Solve the brackets(parenthesis) first.

Inside the brackets, you have to use the P.E.M.D.A.S. formula once again, as if it was a different equation.

16-8[(9)÷9]

Once you've found the solution to the equation 3+6 inside the parenthesis, you divide it by 9.

16-8[1]

Then, since there are no exponents, you multiply.

16-8

Then you subtract.

8
