<span>mostly collect like terms
use associative property which is
(a+b)+c=a+(b+c)
also -a+b-c=(-a)+(b)+(-c) so you can move them around
and remember that:
you just use a general rule
x+x=2x
x^2+x^2=2x^2
3xy4xy=7xy
3x+4x^2=3x+4x^2
you
can only add like terms( like terms are terms that are same name like x
or y are differnt, and like terms have same power exg x^2 and x^3 and
x^1/2 and such
I will oly put the naswers because I don't have much time
first one: 2a+3b+2c
second one: remember that -(-6c)=+6c so the answer is c-10a-2b
third one: -a-8b-5c

Answer:1
Step-by-step explanation:
Answer:
12 pounds
Explanation:
If you were to divide 12.24 from 12 you would get 1.02, which would be the cost of each pound.
Meanwhile, if you were to divide 8.24 from 8 you would get 1.03, which would be the cost of each pound.
So although its only a 1 cent difference and you are technically spending more by buying the 12 pounds, if it were to buy 8 pounds from the cost of each pound for the 12 pounds, you'd only be spending $8.16 vs $8.24.
Because you would multiply 1.02, which is the cost of each pound for 12, by 8 and you would get 8.16.
