Answer:
Step-by-step explanation:
We are given
we can rewrite it as
we know that
2y^2+7y-7 can not be factored
so, we can not reduce this expression
because this is the only way to reduce it
so, we get reduced form as
There's 24 hours in a day
so 24/100 = 0.24 < that is the percentage per hour
first eating - %10. 0.24x10= 2.4hrs eating
free time - 15% 0.24x15= 3.6hrs of free time
homework - 10% 0.24x10 = 2.4hrs of homework
school - 25% 0.24x25= 6hrs of school
and sleeping = 40% 0.24x40=9.6hrs of sleep
add them(hours) all up and you'll get 24!
Answer:
Yes
Step-by-step explanation:
If you observe you can see that 1x=2y
For example 2(x)=4(y)
If you insert this in the others it makes sense making it proportional.
Hope this helps
