Question

Which of these are true equations? Choose all answers that apply:

A. 8+2=5+5

B. 7−2=7+1

C. 10=8+2

Select all that apply:

1. A

2. B

3. C

4. A and C

Answer 1

Equations A (8+2=5+5) and C (10=8+2) are true because both sides of each equation are equal when evaluated. Equation B (7−2=7+1) is false because the two sides are not equal.

Step-by-step explanation:

To determine which of the equations given are true, we can solve or evaluate each one:

1. A. 8+2=5+5: Both sides of this equation equal 10, so this equation is true.
2. B. 7−2=7+1: The left side of the equation equals 5, while the right side equals 8, making this equation false.
3. C. 10=8+2: The right side of the equation adds up to 10, which matches the left side, so this equation is true.

Now, based on the fact that equations A and C are the true ones, the correct answer to the question is '4. A and C'.
