Ellipse is your answer, because if you plug the equation into a graphing calculator and identify the conic, the term ellipse is given-
3.556 is the correct answer
Answer:
First, you have to form simultaneous equation for both of their ages in yerms of a and b :
b = 4a - 12 -------- ( 1 )
a + b = 28 -------- ( 2 )
Next, you will have to solve it by substituting ( 1 ) into ( 2 ) :
a + (4a - 12) = 28
5a - 12 = 28
5a = 28 + 12
5a = 40
a = 8
Then, substitute a = 8 into ( 1 ) :
b = 4(8) - 12
b = 32 - 12
b = 20
Answer:200
Step-by-step explanation: Divied 120 by 60 which gives you 20, so therefore, each ten equals 20.
