Anettt [7]

Answer:

\Large\boxed{21}

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract from left to right. Remember to use the order of operations stands for "Please Excuse My Dear Aunt Sally."

Finally, add & subtract numbers from left to right.

\displaystyle 5+16=21

As a result, the correct answer is 21.

Solve for x<br><br><br> 6x−2(x+4)=12
aev [14]
To solve for x, we will begin by using the distributive property

6x - 2(x + 4) = 12

6x - 2x - 8 = 12

(always remember to sort your negatives!)

Add like terms 

4x - 8 = 12

Add 8 to both sides

4x = 20

Divide both sides by 4

x = 5

Step-by-step explanation:

x = 17(3)

x = 51

Centroids create two segments.

The larger makes up \frac{2}{3} of the total.  

The smaller makes up \frac{1}{3} of the total.
