When t=30, w=0, hence there is no workable solution. It implies that there is no longer any water after 20 minutes. So it is illogical for t=30 minutes.
Equations are mathematical expressions that have two algebraic expressions on either side of an equals (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship.
calculation
A linear relationship exists here. The linear equation's slope-intercept form is as follows: where m is the rate of change (positive if increasing rate and negative if decreasing rate)
2.5 quarts per minute are changed (it is decreasing so m is -2.5)
C is 50 since the initial value is 50 quarts.
incorporating the results' values. y = -2.5x +50
We get y = -2.5x +50 by swapping the variables w and t for y and x, respectively. Where w is the remaining water in the bathtub and t is the passing time in minutes.
