Icant figure out 17 : 3 and 68 : 12 are equivalent
in a pizza eating contest a participant can eat 3 slices of pizza in 2 minutes if he continues at this rate then how many slices of pizza will be eat in 10 minutes?

17:3 is 68:12 simplified

15 slices will be eaten in 10 minutes

Step-by-step explanation:

first off 17:3 is 68:12 simplified (both 68 and 12 go into 4 resulting in 17 and 3)

you have to divide 10 by 2 which will give you 5

and then multiply by 3

to get 15

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
