KINDLY PLEASE HELP ME TO SOLVE THIS..THANK YOU💜 Answer by Solver92311(821) (Show Source):
Let represent the number of hours Maria would take to clean the house alone. Then is the number of hours Jane would take to clean the house alone.
Maria can clean of the house in one hour. Jane can clean of the house in one hour. Working together, they could clean of the house in one hour.
Adding the fractions:
represents the fractional portion of the house that they could clean in one hour working together. Taking the reciprocal:
represents the amount of time that it would take both to clean the whole house, and we know that this is equal to 2 hours, hence:
Solve for to find the amount of time it would take Maria to clean the house by herself, and then calculate to find the amount of time it would take Jane to clean the house by herself. Hint: Multiply both sides of the equation by the denominator on the left, collect like terms, solve the resulting quadratic, and discard any answer less than zero.
