Given:
Total duration of Mariko's social studies class = 5/6 of an hour.
Only 3/12 of an hour has passed.
To Find:
Fraction of an hour remains for Mariko's social studies class =?
Solution:
Converting into minutes
5/6 of an hour =
=>
=>50 minutes
So the total duration of Mariko's social studies = 50 minutes
If 3/12 of an hour passes means
Converting into minutes
=>
=>
=>
=> 15 minutes
15 minutes has passed
Remaining time left is
50 minutes - 15 minutes = 35 minutes left
Now converting into 35 minutes into hours we get
=>
=>
Answer:
hey! This was the only part of mathematics I ever enjoyed! So consider this both of our lucky days: Answer is : (2,7)
Step-by-step explanation:
basically plug in Y to the first equation as sox + 4(-x + 9) = 30
x - 4x + 36 = 30- 3x = - 6
x = 2
then plug that in to Y!
Y = -(2) + 9
so Y = 7
and our answer is : (2,7)

-2log_5 7x = log_5 2
log_5[1/(7x)^2] = log_5 2
log_5(1/49x^2) = log_5 2
log_5(1 - 49x^2) = log_5 2
1 - 49x^2 = 2
You finish.
