<span>Given than 1 pound = 16 ounces, we have a total of 8*16 + 10 = 138 ounces which we must devide among the 3 classrooms. This gives us 138/3 = 46 ounces per classroom, or 2 pounds and 14 ounces per classroom.</span>
C * 5 = 30
Divide both sides by 5
c = 6
2 goes into 400, that is

,
However, 2 goes into 400,
200 times.
The "x" intercept is found when you plug in "0" for "y"
-6x + 3(0) = 18.9
-6x = 18.9 (Divide both sides by -6)
x = - 3.15
(-3.15, 0) is your x-intercept
Now plug in "0" for the x
-6(0) + 3y = 18.9
3y = 18.9 (Divide both sides by 3)
y = 6.3
(0, 6.3) is your y - intercept
