TRUE OR FALSE?
If x=18, is the equation (1/6)x = 3 true or false?
True because (1/6)*(18) = 3.
If we take 18 and divide it into 6 equal groups, each group would have 3.

Lake Elkhorn's SGA is having a bake sale! Each cookie costs $1.50.
a) If the SGA sold 8 cookies, how much money did they raise?
1.50*8 = $12
TRUE OR FALSE?
If x=18, is the equation x-4=16 true or false?
False because if we replace that x=18, our equation would say 18-4=16. This is not true because 18-4=14.

Lake Elkhorn's SGA is having a bake sale! Each cookie costs $1.50.
a) If the SGA sold 12 cookies, how much money did they raise?
1.50*12 = $18
TRUE OR FALSE?
If x=2, is the equation 20-x=22 true or false?
False because if we replace that x=2 our equation will now say 20-2=22, which is incorrect because 20-2=18.
