Answer:
80,640 IN 3
Step-by-step explanation:
The answer is x = 3
The method:
21 - 6x = 27 - 8x
-6 + 8x = 27 - 21
2x = 27 - 21
2x = 6
x = 3
Answer:
31.744 gallons of water
Step-by-step explanation:
Find the amount of water he used in 12 seconds.

31+.744=31.744 gallons
The answer is 60 degrees,cause a straight line is 180
Answer:
(3, -7) and (1, 2) are solutions to the equation
Step-by-step explanation:
Simply replace the (x, y ) pair of values in the equation and see if the equality holds:
Pair (0, -8) :
9 (0) + 2 (-8) = -16 therefore this pair is NOT a solution of the equation
Pair (3, -7):
9 (3) + 2 (-7) = 27-14 = 13 therefore this pair IS a solution of the equation
Pair (1, 2):
9 (1) + 2 (2) = 9 + 4 = 13 therefore this pair IS a solution of the equation
Pair (4, -5):
9 (4) + 2 (-5) = 36 - 10 - 26 therefore this pair is NOT a solution of the equation
