Clearly, wether we're talking about tiles, plants, pages, e-mails, friend or files, the math won't change! :)
Percentages are just special fractions, since they have denominator 100. So, for example, 64% of 75 is given by
So, you divide the number by 100 and then you multiply by the percentage you want. As a last example, 20% of 70 is
And so on with all the others
Answer:
x = 3
Step-by-step explanation:
5x - 14 =1

Step-by-step explanation:
Answer:
n = -11xy, so the answer is G.
Step-by-step explanation:
3x^2−n−4y^2=(3x−y)(x+4y)
Step 1: Add -3x^2 to both sides.
3x^2−4y^2−n+−3x^2=3x^2+11xy−4y^2+−3x^2
−4y^2−n=11xy−4y^2
Step 2: Add 4y^2 to both sides.
−4y^2−n+4y^2=11xy−4y^2+4y^2
−n=11xy
Step 3: Divide both sides by -1.
n=−11xy
