Answer:
55 decrease by 5 is 50, or 55 - 5 = 50.
Step-by-step explanation:
Let x represent the missing number.
When you hear the words decrease, minus, that tells you to subtract.
Before we subtract, if there is a variable, we must do the opposite of subtraction, we need to add.

Which means x = 50 + 5.
50 + 5 = 55.
Therefore, x = 55.
You would take 8.50 and divide it by 12.
to get $0.71

×

To multiply, you multiply across. So it would be 3×1=3 and 10×6=60
Which will result in

but in order to simplify it, you find a common factor. The common factor is 3. 3÷3=1 and 60÷3=20
