35+5t=amount in tank A after t minutes
100-8t=amount in tank B after t minutes
same amount
35+5t=100-8t
add 8t both sides
35+13t=100
minus 35 both sides
13t=65
divide by 13 both sides
t=5
5 minutes
Hii the answer is 29 i’m pretty sure
That would be:-
x^2 + x - 72 = 0
(x + 9)(x - 8) = 0
smallest number is 8
Range is eleven median is 27
