Answer: 45 minutes
Step-by-step explanation:
the first pump takes care of 300 gallons so we need to worry about the remaining 900 gallons. the second pump removes 20 gallons per minute so all u have to do to find how many minutes it would take is divide 900 gallons by 20 gallons a minute which gives you 45
it will take 45 minutes to completely drain the pool
87=(T1+T2+T3+T4+T+T6)/6
87=(93+87+82+86+x+(x-4))/6
87*6=93+87+82+86+2x-4
87*6=344+2x
178=2x
89=x implies 85, 89
Answer: y = 7
Step-by-step explanation:
√8y - 7 = 7
(√8y - 7)^2 = (7)^2
8y - 7 = 49
+7. +7
8y = 56
Y = 7
