Answer:
The Federal taxes of total budget is 30%
C is correct.
Step-by-step explanation:
The chart below summarizes Ralph's annual expenses for the upcoming year.
We need to find the percentage for federal taxes.
First we find total annual budget from chart. We will add all the taxes.
Total annual budget = Federal taxes + State tax + Housing + Food + Medical +
Transportation + Recreation
Total Annual Budget = 18380 + 3448 + 15000 + 4880 + 6652 + 4332 + 3500 +
3260 + 1750
= 61202
Total Annual Budget = $61,202
Federal Taxes = $18,380
Now, we will find the percentage of federal taxes.
% of federal taxes 

Hence, The Federal taxes of total budget is 30%
Answer:
<u>For this equation the value of x is - 2/3</u>
Step-by-step explanation:
1. Resolving the equation 2/3-4x+7/2=-9x+5/6
-4x + 9x = 5/6 - 2/3 - 7/2 (Putting the all the x values on the left)
5x = (5/6 - 4/6 -21/6)
5x = -20/6
x = - 20/6 /5 (Dividing by 5 at both sides)
x = -20/6 * 1/5
<u>x = -4/6 = - 2/3 (Simplifying)</u>
2. Proof of replacing x by -2/3
2/3 - 4 (-2/3) + 7/2 = -9 (-2/3) + 5/6
2/3 + 8/3 + 7/2 = 18/3 + 5/6
10/3 + 7/2 = 6 + 5/6
20 + 21 = 36 + 5 (Multiplying by 6 at both sides)
41 = 41
<u>It means the value of -2/3 for x is correct</u>
