You could put,
19
+ 6
———
25
Then write,
19+6=25
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:

Step-by-step explanation:
1) Remove parentheses.

2) Regroup terms.

Answer:
8
Step-by-step explanation:
Well 2x=16 is the same as x=8 when you divide by 2. So the dot should be on 8.
