Answer:

About 9.52.

Step-by-step explanation:

The question is asking you to simplify this expression. Since I'm not sure whether or not it wants you to fully solve this or not, I will do both ways.

Just simplifying the expression- 12 squared is about 3.4, and 8 squared is about 2.8. Now the expression is 3.4 x 2.8. Now the equation is simplified.

Simplifying and solving the expression- Now all you have to do if multiply the simplified expression. 3.4 x 2.8 = 9.52

Sorry if this a little off, but I'm not if your teacher wants you to round the decimal a certain way or not. Please let me know if it was right or if you have questions :)

What is the sum of 16 quotient of 3

marysya [2.9K]

X + y = 16 (1)
x/y = 3 (2)
-------
x + y = 16
x = 16 - y
1. Substitute x into equation 2
16-y/y = 3
16 - y = 3y
16 = 4y
y = 4
2. Now substitute y into equation 1
x/y = 3
x/4 = 2
x = 12
Therefore, x = 12, y = 4
