Answer: A is the correct answer I am 100% positive
Step-by-step explanation:
<h3>
Answer: x-y years old</h3>
========================================================
Explanation:
Let's use numbers in place of the variables
Let's say Anna is 25 years old and her sister Jane is 5 years younger.
This means Anna was 25-5 = 20 years old when Jane was born.
-------------------------
As another example:
Anna = 37 years old
Jane = 10 years younger
Anna was 37-10 = 27 when her sister was born
--------------------------
The examples show that all we do is subtract the x and y values to figure out how old Anna was when her sister was born.
For the first example, we basically did x-y = 25-5 = 20
The second example was x-y = 37-10 = 27
A variable is placeholder for a number. Think of it as a box where a single number will go inside.
The answer to 40 is C and the answer to 41 is A.
Answer:
a) -2 < 3
b) |-12| < |15| <em>(the absolute value of -12 is 12 so that's comparing 12 to 15)</em>
c) 3 > -4
d) |15| > |-12|
e) 7 > -11
The prime factorization of 576 is 2 x 2 x 2 x 2 x 2 x 2 x 3 x 3 or 2^6 * 3^2
The prime factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2 or 2 ^ 6
