Answer: it will take 5 weeks for both trees to be the sane height.

Step-by-step explanation:

Let x represent the number of weeks it will take the two plants to be the same height.

The first flower is 2 inches tall and it is growing 2.25 inches each week. This means that in x weeks, the height of the flower would be

2 + 2.25x

The second plant is 5.75 inches tall, and it is growing 1.5 inches each week. This means that in x weeks, the height of the flower would be

5.75 + 1.5x

For both flowers to be the same height, the number of weeks would be

2 + 2.25x = 5.75 + 1.5x

2.25x - 1.5x = 5.75 - 2

0.75x = 3.75

x = 3.75/0.75

x = 5
