galben [10]

Answer:

- 120

Step-by-step explanation:

call x is the number you want to find

(3/4 )x + 3 $\frac{1}{2}$ = (2/3)x - 6 $\frac{1}{2}$
(3/4)x + (7/2) = (2/3)x - (13/2)
(3/4)x - (2/3)x = - (13 /2) - (7/2)
(1/12)x = -10
x = -10 / (1/12) = -120

Vlad [161]

Answer:

18 days

Step-by-step explanation:

Here's a short table of heights:

day 0: height = 1

day 1: height = 1 + (1/2)(1) = 3/2

day 2: height = (3/2) + (1/3)(3/2) = 3/2 + 1/2 = 2

The pattern of heights is ...

(day, height) = (0, 1), (1, 1.5), (2, 2)

The plant is growing 1/2 its original height each day, so we can write the equation ...

h = 1 + d/2

We want to find the number of days (d) that result in a height of 10 (ten times the original height).

10 = 1 + d/2

9 = d/2 . . . . subtract 1

18 = d . . . . . multiply by 2

It took 18 days for the plant to grow to 10 times its original height.
