Answer:
x = 2/9
Step-by-step explanation:
3x = 2/3
3*3x = 2
9x = 2
x = 2/9
Check:
3*2/9 = 2/3
6/9 = 2/3
The number here is will be represented as under -
Let the number be x.
Thus, the 5 times the number will be = 5x.
Now, it says, the number is 68 less than 5 times a number.
The equation so formed will be -
5x - 68 = x
4x = 68
x = 68.
Thus, the number will be 17.
Let us re-check the number,
(5 × 17) - 68 = 17
85 - 68 = 17
<em><u>17 = 17. Thus, the number will be 17.</u></em>

Answer:
(d) 192π = π(5)²h
Step-by-step explanation:
A useful first step is to put the given values into the given formula. That is illustrated in choice D.
V = πr²h
192π = π(5)²h
Simple,
take both the hours, and the beginning time they start at,
8:00 AM
For the first painter:
8:00 AM+10 hours...
Beginning at 8..
9,10,11,12,1,2,3,4,5,6
Thus, the FIRST painter will end at 6 P.M.
Now, the second painter:
8:00 AM+6 hours
Beginning at 8....
9,10,11,12,1,2
Thus, the second painter will end at 2 P.M.
1/6 divided by 2 is 1/6 multiplied by 1/2
1/6 * 1/2 = 1/12
1/12 of the shingles for the roof will be in each stack.
