A. x
B. 2 y
C. y
D. 2 x

Answer 1

Jonathan found the value 19/4 or 4 3/4.

Step-by-step explanation:

Jonathan computed the sum 8 3/4 + (-4). To add mixed numbers, you need to convert them into improper fractions. 8 3/4 can be written as 35/4. So, the sum is (35/4) + (-4).

To add fractions with different signs, you need to subtract their absolute values. The absolute value of 4 is 4. Subtracting 4 from 35/4 gives us 35/4 - 16/4, which simplifies to 19/4.

Therefore, the value that Jonathan found is 19/4 or 4 3/4.
