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.
For the question on the picture with -3/2 the answer is x=12, but the one you typed with -3/4 the answer is x=24
Answer: Percent decrease by 50%
to get from 18 to 9, it’s 9/18 which is 1/2, and 1/2 of 100 is 50.
There are infinitely many solutions to this system of equations because they are actually the same. If you add 4 to both sides of the second equation, you get y-4+4=x+4, which simplifies to y=x+4. This is in fact the same as the first equation. Since you are dealing with two lines that lie on top of each other, there are infinitely many solutions.
