Write an equation system based on the problem
"Agatha is five times older than her son, Bob" could be written as:
a = 5b.......(first equation)
"Three years ago, she was nine times older" could be written as:
a - 3 = 9(b - 3)......(second equation)
Solve the equation system
To find the value of b, substitute 5b as a to the second equation
a - 3 = 9(b - 3)
5b - 3 = 9(b - 3)
5b - 3 = 9b - 27
5b - 9b = -27 + 3
-4b = -24
b = -24/-4
b = 6
Her son, Bob, is 6 years old
To find Agatha's age, substitute the value of b to the first equation
a = 5b
a = 5 × 6
a = 30
Agatha is 30 years old
Use the calculator to find:
169^2=169*169=28561
Answer:
No
Step-by-step explanation:
For x and y to have a proportional relationship, then
the ratio of k = 
must be equal for all points
(2, 5) → k = 
= 2.5
(3, 7.5) → k = 
= 2.5
(5, 12.5) → k = 
= 2.5
(18, 8) → k = 
= 2.25 ≠ 2.5
k is not equal for all values , hence no proportional relationship exists
