Answer: 12a-a (hope this helps :)
=12a-1a
=12a+-1a
=a+a+a+a+a+a+a+a+
=a+a+a+a+a+a+a+a+
=11A
let's say it holds "x" gallons of gas.
how much is 1/3 of that? well is just (1/3)x.
how about 1/2 of that? well is just (1/2)x.
we know that
notice, we simply multiplied both sides by the LCD of all fractions, to just do away with the denominators.
A classic example of a difference of squares equation:
x^2 - y^2
This equation consists of two perfect squares, x^2 and y^2. It also has 2 terms. We can factor this equation like this: (x-y)(x+y). If there were more than two terms, it would look different.
Also, the equation x^2+ y^2 is unfactorable. "Difference" means something minus another thing. Therefore, one term has to have a plus sign and one term has to have a minus sign.
In your question, we have determined that A, B, and C are all true, so the letter answer is B.
Zero with aside of 7 plus 3 and 4
We have two variables p and q that need to be found.
p = # of pints
q= # of quarts
16p+32q=1280
- you do not jump into looking for the answer to each variable as it is asking for an equation not to find what p and q is
