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: x=19
Step-by-step explanation:
x=31-12
x=19
Test all answer choices:
A) 0.25+0.20+0.02 = 0.47 - incorrect
B) 0.75+0.02 = 0.77 - incorrect
C) 0.50+0.05+0.02 = 0.57 correct
D) 0.50+0.10+0.02 = 0.62 incorrect
The correct answer is C.
1/6 because 2•1=2 and 3•4=12 and 2/12=1/6
The answer is 10
10-1=9
9*8=72
