2.3 * 80 + 4.7 * 70
Step-by-step explanation:
Answer: OPTION B.
Step-by-step explanation:
Given the following equation:
These are the steps to solve it:
<em>Step 1</em>
Add like terms on the left side of the equation:
<em>Step 2</em>
Apply Addition property of equality, which states that: 
Then, we can add 25 to both sides of the equation:
<em>Step 3</em>
Applying the Subtraction property of equality, we can subtract 
from both sides:
<em>Step 4</em>
Applying the Division property of equality, we can both sides of the equation by 3. Then:
Replace x with the binomial a - 2.
f(a - 2) = [3(a - 2) + 5]/(a- 2)
f(a - 2) = [3a - 6 + 5]/(a - 2)
f(a - 2) = [3a - 1]/(a - 2)
f(a - 2) = (3a - 1)/(a - 2)
Done.
