really mrs sue...
i need help!!!!
15 and 1/2
8.5+7=15.5
To solve this question, we need to set up an equation based on the information provided and then solve it.
Let's assume that Steven's current age is represented by the variable "x". We are told that eight and one-half years ago, Steven was 7 years old. So, we can subtract 8.5 from his current age to determine his age at that time.
Using this information, we can create the equation: x - 8.5 = 7
To solve the equation, we need to isolate the variable "x" on one side of the equation. We can do this by adding 8.5 to both sides of the equation to eliminate the constant term on the left side:
x - 8.5 + 8.5 = 7 + 8.5
This simplifies to:
x = 15.5
Therefore, Steven's current age is 15.5 years old.
