Answer:
<u><em>C, </em></u> Expression B and Expression D
Step-by-step explanation:
<h2><u><em>
Step 1 : Analyzing the question:</em></u></h2>
The regular price of an item at a store is p dollars. The items is
on sale for 10% off the regular price. Some of the expressions
below represent the sale price, in dollars, of the item.
It says " <em>item on sale for 10% off </em>". That means 
or 
.
<h2><u><em>
Step 2 : Looking at the next portion of the question:</em></u></h2>
Expression A: 0.1p
Expression B: 0.9p
Expression C: 1 - 0.1p
Expression D: p - 0.1p
Expression E: p - 0.0p
<u>Expression A</u> doesn't make any sense. It only shows the how
much you save

<u>Expression C: </u> You can't subtract 
from 
<h3>
<em><u>Expression D: </u></em> D makes sense.

Step 3: The answers:</em></u></h2>
<u><em>The answer is C .</em></u>
Answer:
8L/2days = 4L/day
4L/day x 7 days = 28L
Step-by-step explanation:
The "x" intercept is where a line would mark across the "x" axis.
The "y" intercept is where a line would mark across the "y" axis.
X is horizontal and Y is vertical.
Answer:
(-15)/3 = -5
Step-by-step explanation:
(-15)/3
Assume that your positive tiles are yellow, and your negative tiles are red.
The question is asking, "if you take 15 red tiles and split them into three equal groups, how many will you have in each group?"
How can you model the first value of -15? With 15 red tiles.
Let’s model how to divide the tiles into three equal groups by moving one tile at a time into three separate groups until all 15 tiles have been moved.
Step 1.
Start with 15 red tiles, as in the first picture.
Step 2.
Start by moving tiles one at a time to begin creating three new groups.
The middle picture shows the situation after you have moved the first three tiles.
Step 3.
Continue moving tiles one at a time from the original group and stacking them evenly in the three new groups until you have no more tiles to move.
The third picture shows the situation when you have finished.
How many red tiles are in each group? There are five.
Is the answer positive or negative? The answer is negative, because there are five red negative tiles in each group.
Conclusion? (-15)/3 = -5
WDYM? That is already a linear equation.
