<h3>
Answer: 4 people</h3>
Work Shown:
2/5 = 0.4
(10 people)/(1 hour) = (x number of people)/(0.4 of an hour)
10/1 = x/0.4
10*0.4 = 1*x
4 = x
x = 4
She can check out 4 people in 2/5 of an hour.
Note: 2/5 of an hour = (2/5)*60 = 24 minutes
Answer:
I do know that y = 3 and that x = -2, so any system that has that solution is correct.
Step-by-step explanation:
Multiplying the second equation by -2 and adding the equations will cancel out the x variable. The remaining equation is:
10y = 30. Therefore, y must be 3. Substituting y in for the first equation, we get:
6x + 6 = -6. That means x must be -2. I checked my work with the second equation:
-6 - 12 = -18.
The system results in a true statement, so the answer is y = 3 and x = -2.
Answer:
4 quarters
20 Nickels
