For this case, the first thing we must do is define variables.
We have then:
x: number of years of Joan y: number of years of ellen We now write the system of equations:
Solving the system we have:
So that Joan is 21 years old then:
Answer:
joan will be 21 years old in 12 years

Answer:
Choice A, C and E
Step-by-step explanation:
<em>Your table is poorly presented</em>
Given
x y
First, we calculate the constant of proportionality (k)
For (3,1.47)
For (5,2.45)
For (9,4.41)
From the above calculations, the constant of proportionality is 0.49.
So, the usable rows must also have 0.49 as their constant of proportionality
<u>Choice A</u>
--- <em>This is usable</em>

<u>Choice B</u>
--- <em>This is not usable</em>
