Answer:
11 hours is the most she can afford
Step-by-step explanation:
Let x, represent the number of minutes and y represents the number of gallons of water in the tub, then the ordered pairs (2, 30) and (5, 12) satisfies the equation.
Therefore the equation is given by: (y - 30)/(x - 2) = (12 - 30)/(5 - 2)
(y - 30)/(x - 2) = -18/3 x = -6
y - 30 = -6(x - 2) = -6x + 12
y = -6x + 42
Required equation is y + 6x = 42.
Answer:
Tuesday : Total = 30 : 72 = 5 : 12
Step-by-step explanation:
Monday: 42 miles
Tuesday: 42 - 12 = 30 miles
Monday + Tuesday: 42 + 30 = 72 miles
Tuesday : Total = 30 : 72 = 5 : 12

is true if either of

is true, which enough to say that

is also true.
