Answer:
1 ¹/₉ hours
Step-by-step explanation:
Let's say L is Larry's speed, C is Curly's speed, and M is Moe's speed.
1 = 2 (L + C)
1 = 1 ⅔ (C + M)
1 = 1 (L + C + M)
Solve the system of equations. First, simplify the equations:
1 = 2L + 2C
3 = 5C + 5M
1 = L + C + M
Double the third equation and subtract the first equation from it:
2 = 2L + 2C + 2M
1 = 2L + 2C
1 = 2M
M = 1/2
Plugging into the second and third equations, we get:
C = 1/10
L = 2/5
Therefore, the time it takes Larry and Moe together is:
1 = t (L + M)
t = 1 / (L + M)
t = 1 / (2/5 + 1/2)
t = 1 / (4/10 + 5/10)
t = 1 / (9/10)
t = 10/9
t = 1 ¹/₉ hours
It takes them 1 ¹/₉ hours, or 1 hour 6 minutes 40 seconds.

15x10000=150,000
Answer:
First you need to find what x is equal to.
Step-by-step explanation:
Since 3x-5 is what you need to find divide 3 by 3x to get x alone and do the same for -5/ 3 which -1.6666667, and you can estimate it to be -1.67 so x is about -1.67.
Answer:
5 2/3
Step-by-step explanation:
17/3
Take the numerator and divide by the denominator
3 goes into 17 5 times with 2 left over
