15/5 is 3
So then you change the equation to be 12=15z-3 ( don’t forgot the negative sign)
Move the constant to the right side and change the sign
-15z= -3 -12
-3-12 is -15
Divide -15z= -15
Your final answer will be z= 1
Hi there!
Great question! 0.06 is actually SMALLER than 1.
Why?
Because 0.06 is almost half of the whole number. Half of 1 is 0.5, which is larger than 0.06.
Half is smaller than whole, so, therefore, 1 is larger.
Hope this helps!
Message me if you need anything else! I'd be happy to help! :D
