Answer:
B
Step-by-step explanation:
For something to be directly proportional it has to go through the origin (0,0) of the graph.
Answer:
x=12
Step-by-step explanation:
8x6=48 =x
6x6=36
equation= 6x*6-48=x
It can be easily assumed that most information's are already given in the question. Based on those information's, the answer can be deduced.
rt = [(3/4)r] * (t + 12)
4rt = 3r (t + 12)
4rt = 3rt + 36r
4rt - 3rt = 36r
rt = 36r
t = 36
From the above deduction we can conclude that the time taken by Carmen to ride to the market is 36 minutes
Then
Time taken by Carmen to ride home = 36 + 12 = 48 minutes
