Answer:
Add the 2 numbers up together. Thatś how I have learned to do it anyway. maybe someone else has something different.
Step-by-step explanation:
Answer:
I think it’s the second one, 70a+21b sorry if I’m wrong!
Chris sees 6 fish.
Mike sees 3 more fish than Chris.
6 + 3 = 9
So on your bar, you have Chris's number of fish he saw, 6, and you have 3 being added to that on Mike's bar.
The final solution is y=-5/3x-10
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>
