All mutiples of 3 are also mutiples of 6 true or false

That is very false and true! because 3 6 9 12 15 18 21 it skips in and out like a pattern!

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
