Sibyl has seen four more films than Linda. Linda has seen twice as many films as Joel. If Sibyl has seen s films, then in terms of s, what expression can represent the number of films Joel has seen? Can you please explain it?
Answers
Answer 1
Answer:
If Sibyl has seen 4 more films than Linda, then Linda has seen 4 less films that Sibyl. So, you can write the expression L (Linda)=S-4. If Linda has seen twice as many films as Joel, then Joel has seen half the films that Linda has seen. So you can write this at J=1/2L. If L=s-4, then the number of films Joel has seen can be written as 1/2(s-4). I hope this helps!

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 youcan only add like terms( like terms are terms that are same name like xor y are differnt, and like terms have same power exg x^2 and x^3 andx^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
