The answer is 96 min, here is why:
x / 240 + x / 160 = 1
<span>2x + 3x = 480 </span>
<span>5x = 480 </span>
<span>x = 96 min
(</span><span>Drainage rate of first pipe = 480000/240 = 2000 l/min </span>
<span>Drainage rate of second tube = 480000/160 = 3000 l/min </span>
<span>Combined drainage rate = 5000 l/min </span>
<span>Time to drain = 480000/5000 = 96 min. )</span>

Is the area of the burger!
(1/3) bag = (1/4) lb.
multiply by 3 on both sides to get 1 full bag.
3(1/3)b = 3(1/4)
1 bag = (3/4) lb.
The nth term is given by 2ⁿ-1.
The series looks like, 1, 3, 7, 15, 31, 63, 127, ...
Answer:
y + 9 =
(x + 4)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m =
and (a, b) = (- 4, - 9) , thus
y - (- 9) =
(x - (- 4) ) , that is
y + 9 =
(x + 4)
