Commutative Property is a type of swapping property, you switch the numbers and get the same answer. This only works on addition and multiplication (+,x) Here are some example to show you:
3*6=18 = 6*3=18 and 3+6=9 = 6+3=9
0 ≠ 4. The equation is wrong, and has no true solution.
8x + 3 - 10x = -2(x - 2) + 3
<em><u>Distributive property.</u></em>
8x + 3 - 10x = -2x + 4 + 3
<em><u>Combine like terms.</u></em>
-2x + 3 = -2x + 7
<em><u>Cancel like terms.</u></em>
<em><u>Subtract 3 from both sides.</u></em>
0 ≠ 4
The lengths of the sides of the base are 2 ft
This is because the volume is the base times the height
if you take the volume and divide it by the height than you get 4, which means the area of the base is 4
This means that when you multiply the side lengths together you should get 4 and since you know the base is a square (so both sides are the same length) the answer is 2
Answer:
168 books
Step-by-step explanation:
Given
of the remaining books
Required
Determine the total number of books
If the proportion of the English books is 3/8, the the remaining is:
Take LCM
From the question, we understand that:
of the remaining books
This means:
From the question, we also understand that 75 are Chinese books.
The total number of books can then be calculated using:
Substitute 75 for Chinese
Make Total the subject:
