Answer
When \( x = 8 \) and \( y = 11 \), the expression \( 5x + 9y \) equals 139. Additionally, \( 58 + 911 = 969 \), \( 979 + 99 = 1078 \), and \( -\frac{46}{139} \approx -0.330 \).
Solution
To solve the given expressions, we will substitute the values of \( x \) and \( y \) into the expression \( 5x + 9y \) and then calculate the result.
Given:
\( x = 8 \) and \( y = 11 \)
Substitute the values of \( x \) and \( y \) into the expression \( 5x + 9y \):
\( 5(8) + 9(11) \)
Calculate the result:
\( 40 + 99 = 139 \)
Therefore, the result of the expression \( 5x + 9y \) when \( x = 8 \) and \( y = 11 \) is 139.
Next, we will calculate the result of the expression \( 58 + 911 \):
\( 58 + 911 = 969 \)
Then, we will calculate the result of the expression \( 979 + 99 \):
\( 979 + 99 = 1078 \)
Finally, we will calculate the result of the expression \( -\frac{46}{139} \):
\( -\frac{46}{139} = -0.330 \) (rounded to three decimal places)
Therefore, the results of the given expressions are:
1. \( 5x + 9y \) when \( x = 8 \) and \( y = 11 \) is 139.
2. \( 58 + 911 \) is 969.
3. \( 979 + 99 \) is 1078.
4. \( -\frac{46}{139} \) is approximately -0.330.

Simplify this solution The Deep Dive
When you substitute \( x=8 \) and \( y=11 \) into the expression \( 5x + 9y \), you'll find that it equals \( 40 + 99 = 139 \). Nothing like plugging in numbers to get a quick result! Now, for the calculations: \( 58 + 911 \) gives you \( 969 \) and \( 979 + 99 \) equals \( 1078 \). When you subtract \( \frac{46}{139} \) from \( 1078 \), simply convert \( \frac{46}{139} < 1 \) to decimal (roughly \( 0.33 \)) and you get around \( 1077.67 \). Math can be both fun and tricky!
