J=jane's age now
a=amy's age now
a-12=amy's age 12 years ago


j is 7 older than a
j=7+a

12 years ago
amy was 1/2 as old as jamie is now
a-12=(1/2)j

so
j=7+a
sub 7+a for j

a-12=(1/2)(7+a)
times 2 both sides
2a-24=7+a
minus a both sides
a-24=7
add 24 both sides
a=31

j=7+a
j=7+31
j=38


jamie is 38 now

In traveling from a dormitory to a certain city, a student went 1/5 of the way by foot, 2/3 of the way by bus, and the remaining
kykrilka [37]

Answer:

C

Step-by-step explanation:

Now, what we know is that the total distance from the dormitory to the city is 1 if expressed in fraction. What we need to know is the fraction of the journey that is scheduled as the last part.

We can get this by subtracting the fractions of the first two phases from 1.

This goes as follows:

1 - (1/5) - (2/3) = 2/15

Now, we know that the final 8 kilometers constitute a fraction of just 2/5

Hence, we know that 2/15 of the total journey is 8 kilometers.

Let the total journey distance be T. This means that 2/15 of T is 8km

2/15 * T = 8km

T = ( 8 * 15 )/2 = 120/2 = 60km
