Which quantity is proportional to 18⁄3? check all that are true. 90⁄16 36⁄6 72⁄12 6⁄1 36⁄12

36/6, 72/12, and 6/1

Step-by-step explanation:

18/3=6, so we just need to find the fractions that simplify into 6 (we reduce fractions by dividing the numerator and denominator by the greatest common factor, in this case the number must be whole, so we are just going to divide the numerator by the denominator). 90/16=5.625, it does not equal 6, so it is not proportional to 18/3, this is also true for 36/12=3. 36/6=6 so it is proportional, so is 72/12=6 and, obviously 6/1=6 so it, too, is proportional to 18/3.

x+y = 29, 5x + 2y = 100

i'm guessing it was a multiple first option was the correct answer

all but the second one

step-by-step explanation:

cuz that one goes over 180
