Answer:
Equivalent fraction of
Two fractions are equivalent fractions. when they represent the same part of a whole. Since equivalent fractions do not always have the same numerator and denominator, one way to determine if two fractions are equivalent is to find a common denominator and rewrite each fraction with that denominator.
so you read 12 + 13 = 25 books in total, and 12 nonfiction ones.
if we take 25 to be the 100%, what is 12 off of it in percentage?
If 50 miles, is 100%, what is 21miles off that in percent?
well
To solve this problem, we need to get the variable x alone on one side of the equation. To begin, we are going to use the distributive property twice on the left side of the equation to expand the multiplication and get rid of the parentheses.
4(x-1) - 2(3x + 5) = -3x -1
4x - 4 -6x - 10 = -3x - 1
Next, we should combine like terms on the left side of the equation. This means we should add/subtract the variable terms and the constant terms in order to simplify this equation further.
-2x - 14 = -3x - 1
Then, we have to add 3x to both sides of the equation to get the variable terms all on the left side of the equation.
x - 14 = -1
After that, we should add 14 to both sides of the equation to get the variable x alone one the left side of the equation.
x = 13
Therefore, the answer is 13.
Hope this helps!
Answer:
Multiplication...
Multiplication is just like adding a number to itself multiple times
For example: 3x3 is the same as 3+3+3
Division...
Division is basically splitting up a number between amother lower number, (it might be pretty difficult if you don’t know how to multiply though...)
Start by Rephrasing/re-ordering the equation (9/3 looks like 3*[?] =9)
1) Figure out what Factors equal 9 (by looking at a multiplication table or by adding up like described earlier)
2) You have your answer
(this took way too long to write and you’re probably an idiot if you’re actually in middle school...smh) I can write a different answer if you meant long division, or something else
