Work and time are inversely proportional to each other. Then the time taken by Anita and Chao will be 3 hours and 26 minutes.
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Anita can clean a typical pool in 8 hours.
Chao can clean a typical pool in 6 hours.
Work and time are inversely proportional to each other. Then we have
Let x be the time taken.
1/x = 1/6 + 1/8
1/x = 7 / 24
x = 24 / 7
x = 3 hours and 26 minutes

The solution to the equation is n = -2.
To solve the equation 30 = -5(6n + 6) step-by-step, follow these procedures:
Step 1: Distribute the -5 on the right side:
30 = -5 * 6n - 5 * 6
Step 2: Simplify the right side:
30 = -30n - 30
Step 3: Move constant term to one side:
30 + 30 = -30n
Step 4: Combine like terms:
60 = -30n
Step 5: Divide both sides by -30 to isolate 'n':
n = 60 / -30
Step 6: Simplify the right side:
n = -2
The solution to the equation is n = -2.
