Ava Ethan Jacob and Samantha are cousins. One of them is 10 years old, one of them is 20 years old, one of them is 30 years old and the other one is 40. The sum of Ava's age and Ethan's age is 50. The sum of Ethan, Jacob and Samantha's age is 60. If Samantha is older than Jacob, how old is Samantha

answer: it actually depends on which is the independent variable and which is the dependent variable. let us say we're looking at a linear equation. y=2x+3. we theoretically could switch the equation to be x=(y-3)/2 and it would be the same line. so either a causes b or it can be that b causes a. so technically the answer is false

step-by-step explanation:

can you post the graph?

hi there!

not proportional because the 42 does not go into 120 and 3 does not go into 8.

correct proportion: $40/1 ticket.

the reason i say this is because 40/1 is simplified and it evenly goes into 120/3.

hope this : )
