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.
50 + 5 = x
Which means x = 50 + 5.
50 + 5 = 55.
Therefore, x = 55.
