Option 4: D

Answer 1

The correct method to solve the equation 3d + 10 = 40 is to subtract 10 from both sides and then divide both sides by 3, leading to the solution d = 10.

Step-by-step explanation:

To solve the equation 3d + 10 = 40, we should follow these steps:

1. Subtract 10 from both sides to isolate the term with the variable on one side of the equation, which gives us 3d = 30.
2. Divide both sides by 3 to solve for d, which gives us d = 10.

Therefore, the correct answer is B) Subtract 10 from both sides, then divide both sides by 3. This method simplifies the equation properly and allows us to find the value of d.
