Answer:
A) $29.68
B) $5.60
Step-by-step explanation:
<u>Part A Explanation)</u>
To find the total cost including tax, you must multiply the total cost by .06 because .06 out of 1 is 6%. <em>Quick explanation on percentages.</em>
<u><em>DO NOT FORGET TO ADD THE TOTAL COST</em></u>
28.00 + (28.00 * .06) = 29.68
<u>Part B Explanation)</u>
This is asking only for the tip, not including the total cost. However, we need the total cost to calculate the tip.
28.00 * .20 = 5.6
<em>.20 out of 1 is 20%</em>
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>
