Yola got the better deal
Answer:
1st= 47/7 or 6.71
2nd= 48/7 or 6.857
Step-by-step explanation:
1st number =X and 2nd number = Y
According to question, X+7=2Y
20+Y=4X
X=2Y-7 (from 1st condition)
putting in it second
20+Y=4(2Y-7)
20+Y=8Y-28
20+28=8Y-Y
48=7Y
Y=48/7
so X=2(48/7)-7
=96-49/7
47/7
You can either write 2.4 as 12/5 ( an improper fraction) or as 2(2/5) (a mixed number).
Hello!
The number of tickets is dependent on age, so age is the independent variable.
