18 - (1/2×18 + 1/3×18)
18 - (9 + 6)
18 - 15 = 3 pints left
7 3/4 - 3 = 4 3/4
the answer is 4 3/4 pints (or 5 pints if they can only buy whole ones)

Hello :
the equation 3x^2+4x-7=0 has 2 solutions because : ac <span>< 0
a = 3 b=4 c= -7
</span>Δ = b²-4ac....... b² ≥ 0 and -4ac > 0 ..... (ac < 0 )
coclusion : Δ>0.....(2 solutions)
The answer would be 12.4 .
