The pizza originally have 30 slices.
What is linear equation?
An equation in which the highest power of the variable is one is known as linear equation.
We will find number of pizza slices as shown below:
Let pizza originally have x slices.
Adam eats 20% of a pizza
= 0.2x
Bethany eats 1/3 of pizza
=1/3(x)
Charlie eats the remaining 14 slices
0.2x+1/3(x)+14=x
14 = x - 0.2x - 1/3(x)
14 = x - x/5 - x/3
14 = (15x - 3x - 5x)/15
14*15 = 7x
By dividing both sides by 7, we get
30 = x
x = 30
Hence, the pizza originally have 30 slices.

The answers are A, C, and D. B is not a correct answer because 4 times 11 is not 42
<span>(6k+10) (4k+5) is not an equation. Or, did you unintentionally leave off "=0?"
Thus, we cannot find a value for k.
If we set </span><span>(6k+10) (4k+5) = to 0, then the roots would be solutions of 6k+10=0 and 4k+5=0. They are {-5/3, -5/4}</span>

Answer:</h3>
-y³ -6y²x +30
<h3>
Step-by-step explanation:</h3>
When parentheses are eliminated and the y variable placed first in each term, the expression simplifies to ...
... 15 -7y²x -y³ +y²x +15
Arranging like terms together, we have ...
... -y³ +y²x(-7 +1) +(15 +15)
... -y³ -6y²x +30
_____
The two different 3rd-degree terms can be expressed in either order. I have chosen to list the term with the largest exponent first. The expression could also be written with the same-degree terms in "lexicographical order", meaning the expression would be written ...
... -6xy² -y³ +30
