After 40 minutes, Ralph has already painted (40/60)/12=1/18 of the fence
Lisa's speed is 1/15 fence/hour, Ralph's speed is 1/12 fence/hour, hence when they help each other their combined speed is 1/15+1/12=3/20
Thus we need to solve 3/20*x=17/18 thus x=170/27 hours (approx 6 hours 15 mins)
Answer:
(0,-6)
Step-by-step explanation:
recall that the y-intercept is simply the point where the line crosses the y-axis at x = 0.
to find the y intercept, we simply substitute x=0 into the equation and solve for y
12x - 10y = 60, when x = 0,
12(0) - 10y = 60
-10y = 60
y = 60 / (-10)
y = -6
hence the coordinate of the y - intercept is (0,-6)
Answer:
No
Step-by-step explanation:
there are 4 cups in a quart, so 4 x 3 = 12 cups, so no she doesn't have enough glue to fill all 24 empty bottles
Answer:
(0,-1)
Step-by-step explanation:
I used substitution but you still get the same answer so it doesn't really matter. Unless it's asking you to show you're work.
