Which statement describes the lines whose equations are y=1/3x+12 and 6y=2x+6
ICE Princess25 [194]
First, you should solve both equations for the same variable. Since the first one is already solved for y, solve the second equation for y as well.

6y = 2x + 6   Divide both sides by 6
y = \frac{1}{3}x + 1

You can see that both lines have a slope of \frac{1}{3}.
Lines that have the same slope are parallel lines.

Erwin had 2 5/12 gallons of lemonade. He spilled 11/12 gallon of lemonade. How much lemonade dose he have left? Write in simples
xz_007 [3.2K]

Answer:

Erwin have 1 \frac{1}{2}   gallons of lemonade left

Step-by-step explanation:

<u><em>Erwin had 2 5/12 gallons of lemonade. He spilled 11/12 gallon of lemonade. How much lemonade dose he have left? Write in simplest form</em></u>

<u><em /></u>

All we need to do is to subtract 11/12 from 2 5/12. But to do this, we will convert 2 5/12 to improper fraction

converting 2 5/12 to improper fraction yields : 29/12

Lemonade have left = Total lemonade - lemonade spilled

                         =          29/12 -  11/12

                               

                         =     18/12

Lemonade have left =18/12

But we can reduce 18/12 to its lowest term

18÷6/ 12÷6      =     3/2

       Lemonade have left = 3/2

We can change to 3/2 to a mixed number to give us 1 \frac{1}{2}    

Therefore Erwin have 1 \frac{1}{2}   gallons of lemonade left
