Using given information we have to fill the blank spaces for respective parts:
<u>Part(A): Original ratio of saved to total money per paycheck </u>
Answer: 
Explanation: Original payment was 200 and saving amount is 1 tenth which is 200*(1/10)=20. Hence ratio is 20/200
<u>Part(B): Final ratio of saved to total money per </u>paycheck___________________
Answer: 
Explanation: He also saved money more than 200 represented by x so the new ratio becomes (x+20)/(x+200)
<u>Part(C): Final amount saved per </u>paycheck______________________________
Answer: x+20
Explanation: Final saving is just 20 and extra money over 200 so final saving is (x+20).
Answer:
4x^2 -8
Step-by-step explanation:
f(x)=3x^2-9
g(x)=x^2+1
(f+g)(x)=3x^2-9 +x^2+1
Combine like terms
= 4x^2 -8
Solution:
we are given that
The difference of two numbers is equal to 0.6.
Let the numbers be x and y so we can write

Their quotient is also 0.6.
so we can write

Now solve these two equations together we get





Hence the numbers are -1.5 and -0.9
Answer:
B
Step-by-step explanation:
2(x-4) = 2x - 8
C). In step 2, he needed to divide both sides of the equation by 5.
