Final answer:
The first step to solving the equation 5.2 + 3 = 8 is subtracting 3 from each side, resulting in 5.2 = 5, which simplifies the equation and prepares it for further solving.
Step-by-step explanation:
The correct first step for solving the equation 5.2 + 3 = 8 is C) Subtract 3 from each side. This step will isolate the variable on one side of the equation, allowing us to solve for it. By doing the same operation to both sides of the equation, we maintain the balance and equality of the equation.
Here is how you would perform this step:
- Start with the original equation: 5.2 + 3 = 8.
- Subtract 3 from both sides: (5.2 + 3) - 3 = 8 - 3.
- Simplify both sides: 5.2 = 5.
After this step, you can move on to check the solution to ensure it is reasonable and makes sense.
