You plug in 1,2,3 and so on in the X and you graph , i think
Answer:
Team A: 25 players
Team B: 24 players
Step-by-step explanation:
Team A:
to find the total # of players of the team we need to set up a fraction. 5 out out of an unknown number of players is equal to 1/5, so we set it up as:
then we cross multiply to get
x*1 = 5*5
x=25 players
Team B
similarly to Team A
cross multiply to get
x*1=3*8
x= 24 players
You aren't trying to find x you are trying to find the inequality to help give possible answers for x. 42<x or x<42
Answer:
Pamela = 30
Jiri = 40
Step-by-step explanation:
Two equations needed:
J-10 = P
P+J = 70
Plug and solve:
(J-10) + J = 70
2J - 10 =70
2J = 80
J = 40
40 - 10 = P
P=30
