Final answer:
To find the number of roses in the blue vase, we double the number of roses in the red vase. Since the red vase has 5 roses, the blue vase contains 10 roses.
Step-by-step explanation:
The student's question is about determining the number of roses in the blue vase given certain conditions about the number of flowers in vases. We know that each vase has 12 flowers, the red vase has 7 tulips, and thus 5 roses because the total is 12. The blue vase has twice as many roses as the red vase, so we need to double the number of roses in the red vase to find that number.
Since the red vase has 5 roses, the blue vase will have twice as many, which is 10 roses.
Here's the calculation step by step:
- Subtract the number of tulips from the total flowers in the red vase to find the number of roses: 12 flowers - 7 tulips = 5 roses.
- Multiply the number of roses in the red vase by 2 to find the number in the blue vase: 5 roses x 2 = 10 roses.
