E(t) is the elevation Maria is at at t minutes.

The expression to calculate the elevation is 1200 + 40t.

E(t) = 1200 + 40t

E(15) means the elevation Maria is at at time 15 minutes.

E(15) = 1200 + 40(15)

E(15) = 1200 + 600

E(15) = 1800

E(15) = 1800 means that Maria is at an elevation of 1800 ft after 15 minutes.

The ages of three siblings combined is 27. The oldest is twice the age of the youngest. The middle child is 3 years older than t
kondaur [170]

Answer:

the oldest sibling is 12 years old.

The middle child is 9 years old.

The youngest child is 6 years old.

Step-by-step explanation:

Let the age of the youngest child be x

Then the oldest child will be 2x.

The middle child will be x + 3.

Since the combined age is 27;

x + 2x + x + 3 = 27

4x = 27 - 3

x = 24 / 4

x = 6

now 2x = 12 and x + 3 = 9
