Answer:
A
Step-by-step explanation:
(7 - 4n) x 6 is the same as 6(7 - 4n)
Expand to become:
6(7) + 6(- 4n)
42 - 24n is your answer.
First, remove the parentheses
-7+2x+7=-7
Cancel the equal terms.
2x+7=0
Subtract 7
2x= -7
Divide both sides by 2
Final answer is:
X= -3.5
Its simply just 8 minus 25 to find x but there is no fraction.
Its simple really. If say a person bought a sandwich for $5.00, and the tax was 7%. You would have to multiply the amount of the sandwich to 0.07. Doing this would tell you how much the tax is. Then you would simply add them to get your total. This also applies with tip, markup, and discount.
