(120) - (-120) = 240 ? TRUE--------------------------------------------------------------O-----------------------------------------------------------------------------------FALSE
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The given equation is 120 - (-120) = 240. When subtracting a negative number, it is the same as adding its positive counterpart. So, -(-120) becomes +120. Therefore, the equation simplifies to 120 + 120 = 240, which is true.

FRACTIONS 2 1/2 + (-1 4/5) =
- A.
  
  7.1
- B.
  
  9.0
- C.
  
  3.4
- D.
  
  3.5
Correct Answer
A. 7.1

Explanation
The correct answer is 7.1 because when we add 2 1/2 and -1 4/5, we first convert the mixed numbers to improper fractions. 2 1/2 becomes 5/2 and -1 4/5 becomes -9/5. Then, we find a common denominator, which is 10. We multiply the numerators by the same factor to get 25/10 and -18/10. Finally, we add the fractions together to get 7/10. Converting this to a decimal, we get 0.7, which is equivalent to 7/10. Therefore, the answer is 7.1.
