Answer:
-5 + (-9) = -14
Step-by-step explanation:
We are told in the question that:
Bob lost 5 points on page one of his math test and he lost 9 points on page two of his math test.
To lose a point would mathematically mean that the point lost would carry a negative sign, making that point a negative integer.
Hence, the statement Bob lost 5 points on page one of his math test and he lost 9 points on page two of his math test is expressed Mathematically as:
-5 + (-9)
In Mathematics:
+ (-) = + × - = -
Hence,
-5 + (-9)
= -5 - 9 = -14
Therefore, the equation that best describes Bob progress on his math test is:
-5 + (-9) = -14
