Answer:
14
Step-by-step explanation:
14
4 / 0.80 = 12 / x...cross multiply
4x = 0.80 * 12
4x = 9.6
x = 9.6 / 4
x = 2.4.....12 apples cost $ 2.40
5/8 = .625
531.25 / .625 = 850
850 - 531.25 = $318.75
#7 is the easiest one.
a + bi = -9 + 4i
see the expression on either side matches up so..
a = -9 and b = 4
