Answer:
x = 9
Step-by-step explanation:
First step, divide both sides by pi to get rid of it entirely; you should be left with x - 8 = 1 (because when you divide a value by itself, you always get 1, so pi divided by pi gives you 1)
Second step, add 8 to both sides, leaving you with x = 9
Suppose that John has a pen that costs $5 and he has 9 similar pens. The total cost of the pens that John has is equal to the cost of his bag. If the cost of the bag is $45, write the verbal model of the situation.
So, cost of each pen = 5
Number of pens = 9
Total cost = 5 * 9
But, it is given that the total cost = cost of the bag and
cost of the bag = 45
So, total cost = 45 and
5 * 9 = 45.
60 is 12% of what number
60 = 0.12x
60 / 0.12 = x
500 = x......so 60 is 12% of 500
