Answer:
12
Step-by-step explanation:
60 divided by 5 is 12, so Bobby jo would give her teachers 48 and 12 to her family
BC = 18
AB = AC, hence
8x - 4 = 5x + 11 ( subtract 5x from both sides )
3x - 4 = 11 ( add 4 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
BC = 4x - 2 = (4 × 5 ) - 2 = 20 - 2 = 18
