4 days
donvert 3 and 1/3 to imporopoer
3 and 1/3=3+1/3=9/3+1/3=10/3
divide 10/3 by 4
remember that divide by 4 means multiply by 1/4
10/3 times 1/4=10/12=5/6
each day spends 5/6 hour (about 50 mins)
First lets convert 3 1/3 into the improper fraction: 10/3
Then lets divide 10/3 by 4 which is equal to 10/3 * 1/4
which is equal to 5/6 hours per day!

Answer:
what are the values of X?
Answer: 14 Units
Step-by-step explanation: Subtract (10-2) and (11-5)
Hello!
1) -3x - 4 = 23
-3x = 23 + 4
-3x = 27
x = 27 : (-3)
x = -9
2) x/2 - 12 = -4
x - 24 = -8
x = -8 + 24
x = 16
3) 6a + (-1) = 10
6a - 1 = 10
6a = 10 + 1
6a = 11
a = 11 : 6
a = 11/6
4) -(x + 2) = 12
x + 2 = -12
x = -12 - 2
x = -14
5) 7a + 12 = 10
7a = 10 - 12
7a = -2
a = -2 : 7
a = -2/7
6) -4(a + 2) = 12
a + 2 = -3
a = -3 - 2
a = -5
Good luck! :)
