Maria = x
Tom = y
Use substitution
x+y=30
2y=x
2y+y=30
3y=30
y=10
Tom is 10 years old.
x+y=30
x+10=30
x=20
Maria is 20 years old.
The unit rate is 10:1 because unit rates are out of 1
You would find that by dividing 20 and 2 by the same number to get to one for this specific problem. 20 divided by two is ten and two divided by two is one. So that is your answer for part b. I can’t draw a graph however so sorry
Answer:
The greater value of the given set is 98.43.
Explanation:
Here the units of the distance given for all the data is miles(mi).
So, the greater value is that value which has higher magnitude.
Values are 79.47,54.28,65.5 and 98.43
Values in their increasing order is given by
54.28 < 65.5 < 79.47 < 98.43
Values in their decreasing order is given by
98.43 > 79.47 > 65.5 > 54.28
So, the greater value of the given set is 98.43.
