Question

Select all equations that are equivalent to S8 = 3 - (4 + 12).

a. 5 + 6 = 3 - (4 + 12)
b. 4 - 9 = 3 - (4 + 12)
c. 2 + 3 = 3 - (4 + 12)
d. 6 + 2 = 4 + 15

Answer 1

None of the given equations are equivalent to S8 = 3 - (4 + 12).

Step-by-step explanation:

To check which equations are equivalent to S8 = 3 - (4 + 12), we need to simplify the expression on the right side of the equation first.

S8 = 3 - (4 + 12)

S8 = 3 - 16

S8 = -13

Now, let's check each equation:

1. 5 + 6 = 3 - (4 + 12) - This equation is not equivalent. The left side of the equation is 11, but the right side is -13.
2. 4 - 9 = 3 - (4 + 12) - This equation is not equivalent. The left side of the equation is -5, but the right side is -13.
3. 2 + 3 = 3 - (4 + 12) - This equation is not equivalent. The left side of the equation is 5, but the right side is -13.
4. 6 + 2 = 4 + 15 - This equation is not equivalent. The left side of the equation is 8, but the right side is 19.

None of the given equations are equivalent to S8 = 3 - (4 + 12).
