Answer:
1218.58
Step-by-step explanation:
This is how you can solve it;
5 = 15y
5 ÷ 15 = y (did the inverse operation of the variable)
0.33 = y or y = 0.33 (rounded to the nearest hundredth)
To check your answer just substitute the value of y in the equation;
5 = 15y
5 = 15(0.33)
5 = 5
so your answer is correct! :D Hope that helps!<span />
Answer:
Step-by-step explanation:
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.
