Based on the CPI, the expected price is
$12.75 * 193/100 = $24.61
The actual price is $28.50 -24.61 = $3.89 more than expected. The appropriate choice is ...
b. The actual price is $3.89 higher than the expected price.
Answer:
The answer is the first one
Step-by-step explanation:
Correct me if I’m wrong and sorry if you got it wrong
(x + 2)/2 = (x - 6)/10
5(x + 2) = x - 6
5x + 10 = x - 6
5x - x = -6 - 10
4x = -16
x = -16/4 = -4
x = -4
They want you to combine the variables. So
−12x4 + 7x3 + 6x4 − 2x3 =
<span>5x3 − 6x4
</span>So you combine the coefficients, not the variable number, for instance -12+6=-6, and then you simply put the variable in the same place it was. You don't do anything else with it except what I just showed you : )

9x² - 8x - 6 is the answer
