A college student needs 11 classes that are worth a total of 40 credits in order to complete her degree. the college offers both 4-credit classes and 3-credit classes. write a system of equations that can be used to determine f, the number of 4-credit classes the student can take to complete her degree and t, the number of 3-credit classes number of four credit classes =
number of three credit classes =

4 & 3

step-by-step explanation:

factor of 108=2×2×3×3×3=2×2×3^3=the number is 4 because 2 only occurs 2 times and 2×2=4 and factor of 2187=3^3×3^3×3=the number is 3 because 3 onlyvoccur 1 time.

29 mil

step-by-step explanation:

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
