Answer:
2 hours
Step-by-step explanation:
If Thomas can paint 1/3 = 2/6 of the room in a hour and Brian can paint 1/6 of the room in an hour. Which means in an hour they can collectively paint 3/6 = 1/2 of the room. Now you need to find how long it would take then to paint 2/2 of the room. Knowing that 1/2+1/2 = 2/2, it would take them 2 hours to paint the room together
Answer:
y = 5x
Step-by-step explanation:
since y varies directly as x then the equation connecting them is
y = kx ← k is the constant of variation
to find k use the condition y = 60 when x = 12, then
k =
=
= 5
y = 5x ← is the equation of variation
Answer:
12x - 12
Step-by-step explanation:
4(3x)= 12x
-2 x 6 = -12
And since you are taking away 12 it works.

Step-by-step explanation:
Hey there!
To plot a fraction on a graph you have to turn it into an improper fraction. In this case, the improper fraction for 2 2/3 is 8/3 and the improper fraction for 1 7/9 is 16/9.
*Note: To find the improper fraction of a fraction you must multiply the denominator by the whole number and then add the numerator.
With these two improper fractions...
8/3
16/9 (Simplify it down to 8/3 since both 16 and 9 go into 3)
You can now graph it. To graph, the numerator tells you how many times to go up and the denominator tells you how many times to go right. <u>IF IT'S NEGATIVE IT WILL DO THE OPPOSITE</u><u> </u><u>IF THE NUMERATOR IS NEGATIVE IT WILL GO DOWN INSTEAD OF UP AND IF THE DENOMINATOR IS NEGATIVE IT WILL GO LEFT INSTEAD OF RIGHT.</u>
8/9 means you need to start at the origin, (0,0) and go 8 up and 3 to the right. 8/3 means you start at the origin and go 8 up and 3 to the right. You will almost always start at the origin.
I really hope this helps :)
