because 3 x's and 2 y's are being multiplied.

<h3>For this explanation, I will be utilizing the hidden exponent of 1.</h3>

<em><u>You can put a hidden exponent of 1 to each variable without an exponent, and the value will remain the same.</u></em>

Merely add the exponents of the values with the same base number, or coefficient. —> <em>like terms</em>

X^1 times X^1 times X^1 is X^3, and Y^1 times Y^1 is Y^2.

Our final answer is X^3 Y^2.

Like the first expression, we can add a hidden exponent to each <u>VARIABLE,</u> not number.

2 times 3 is 6, and X^1 times X^1 is X^2, and Y^1 times Y^1 times Y^1 is Y^3.

Our final answer is 6X^2 Y^3.

first subtract the last equation from the first. this gives:-

-x + y = -8 .....................(1)

Then multiply the first equation by 2 and add it to the 2nd equations This gives

9x = 18

so x = 2

and from equation (1) y = -8 + 2 = -6

Substituting for x and y in the second equation

z = (24 -5(2) -12) / 2 = 1

Answer is choice b.

Volgvan

Answer:

47.14 in³

Step-by-step explanation:

Here is the complete question

Jenny used plastic cone shaped cups to serve punch. The cups were 6 inches in diameter and 5 inches tall. What was the volume of each cup?

Volume of a cone = $\frac{1}{3}$ πr²h

π = 22/7

Radius = diameter / 2 = 6 /2 = 3 inches

(1/3) x (3^2) x (22/7) x 5 = 47.14 in³
