Answer:
R8.70
Step-by-step explanation:
2 oranges = R1.45
1 orange = 1.45 ÷ 2 = 0.725
12 oranges = 0.725 x 12 = 8.70
16 * 12 = 192 dimes should be your answer.
S^2 + 9s - 142 > 2000
s^2 + 9s - 142 - 2000 > 0
s^2 + 9s - 2142 > 0
(s-42)(s+51) > 0
s - 42 > 0
s > 42
s + 51 > 0
s > -51.......will not work
answer is : s > 42
9=3^2
3^(2x)=(3^2)^(3x-4)
3^(2x)=3^(6x-8)
2x=6x-8
0=4x-8
8=4x
2=x
