Essentially, what you need to do is ensure that both sides cancel each other out to make 0 = 0
An example:
2(x + y) + 4 = (4x + 4y + 8)/2
2x + 2y + 4 = 2x + 2y + 4
0 = 0
18 times 4 = 72
Because 5000 times 4 = 20,000
The change in temp. is -72degrees
Answer:
Substitution property of equality
Step-by-step explanation:
Given
and 
Then
Required
State the property
From the list of options, (d) answers the question.
This is so because:
Substitution property of equality states that
If 
then 
In other words, both can replace one another.
So if , then 2y + 1 can be substituted for x in
So:
becomes
<em>Hence, it is substitution property of equality</em>
The first one is correct :-)
The interval from $9 to $10 contains the largest number of sandwich prices. Option B
<h3>Which is a correct statement regarding sandwich prices, based on the histogram?</h3>
Generally, A graph known as a histogram displays the frequency of occurrence of numerical data via the use of rectangles. The frequency of a variable's distribution is shown by its position along the vertical axis, which is the height of a rectangle (the amount, or how often that variable appears).
In conclusion, The greatest number of sandwich costs may be found in the range from $9 to $10. Alternative B
