Answer:
Step-by-step explanation:
45.6
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!
Simplifying
5x + -9 = 38
Reorder the terms:
-9 + 5x = 38
Solving
-9 + 5x = 38
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9' to each side of the equation.
-9 + 9 + 5x = 38 + 9
Combine like terms: -9 + 9 = 0
0 + 5x = 38 + 9
5x = 38 + 9
Combine like terms: 38 + 9 = 47
5x = 47
Divide each side by '5'.
x = 9.4
Simplifying
x = 9.4
