A variable is an unknown like x so
first we start with
x=8
then we subtract (because you must add to reverse subtraction)
x-2=8-2
x-2=6
then we divide ( because you must multiply to reverse division)
(x-2)/3=6/3
(x-2)/3=2
find x
To find the hypothenuse use Pythagorean theorem: 13²+5²=h²,
h=√13²+5²=13.93cm = hypothenuse.
1) 12p+12q 2) 11p-11q 3)2p-10q
Answer:
It is similar because you have to always have the same numerator in adding or subtracting fractions. Adding fractions and subtracting mixed numbers is different because when u have a mixed number you have to simplify it to its lowest terms to make it easy to tell if it's a whole number or mixed.
