Answer: 3y⁴(y² + 5)(y - 1)(y + 1)

Pipe A can fill 3 tanks in 8 minutes. Pipe B can fill 5 tanks in 10 minutes. How long will it take for them to fill a single tan

weqwewe [10]

Answer:

8/7 min = $1 \frac{1}{7} minutes$

Step-by-step explanation:

A rate 2 2/3 = 8/3 min per tank

B rate 2 min per tank

thus:

A rate = 3/8 tank per min

B rate = 1/2 tank per min

A+ B = 3/8 + 4/8 = 7/8 tank per min

7/8 x = 1

x = 8/7 min
