Final answer:
To evaluate the expression (3/7)r + (5/8)s with r=14 and s=8, substitute the values and calculate each term to get 6 + 5, which equals 11.
Step-by-step explanation:
The question asks to evaluate the expression (3/7)r + (5/8)s given the values r=14 and s=8. To solve this, follow the steps below:
- Substitute the given values into the equation: (3/7)×14 + (5/8)×8
- Calculate each term separately: 3/7×14 = 6 and 5/8×8 = 5
- Add the results of each term to get the final answer: 6 + 5 = 11
Therefore, the value of the expression when r=14 and s=8 is 11.
