3(x-9)=30
3(x-9)+9=30+9
3x/3=39/3
x=39/3
x=13

You have to show a new line for each operation when the directions call for step by step.

8/11 x (5/9 - 1/6) ÷ 1 5/9​
Oksana_A [137]

Answer:

28/165

Step-by-step explanation:

You always use the order of operations, and the order of operations says to solve parentheses first, so you would solve 5/9 - 1/6, and get 7/18.

You would do exponents next, if there were any, but there is not, so you move on to the next operation(s).

The next operations are multiplication and division. From left to right, multiplication is first, so you solve 8/11 x 7/18 and get 28/99. Then, there is a division problem to solve. The problem is 28/99 ÷ 15/9. If you solve that correctly, you will get the answer 28/165.

The next step would be to simplify 28/165, but it cannot be simplified, so you are left with the answer 28/165.

What is the area of the circle?
Bumek [7]

Answer:

363

Step-by-step explanation:

Formula for area of a circle

A = πr^2

Where r = radius

The circle has a given radius of 11

To find the area of the circle we simply substitute r in the formula with the value of the radius (11)

( Also note that the question says to use 3 for π )

A = πr^2

π = 3

r = 11

Substitute values in formula

A = (3)(11)^2

11^2 = 121

A = 121(3)

121(3) = 363

A = 363
