To formulate the equation that shows the cost of 10 pounds of potatoes is 8 dollars we proceed as follows;
suppose the cost 1 pound is x;
thus,
total cost=(amount in pounds)*(price of one pound)
total cost=$8
amount=10 pounds
cost of one pound=x
thus the equation is;
8=10x
Answer:
Since we have a^7 on the Numerator and after simplification... No "a" was left in the expression. It simply means that all a's in the numerator was eliminated and 2a's were left in the denominator.
To eliminate a^7 and still have 2a's as a remainder in the denominator... 'n' must be equal to 9
So
n=9
x + 3 = 6
Subtract 3 from both sides:
x = 3
