Answer:
3402
Step-by-step explanation:
7 yards is 21 feet, so Diana's cost is ...
(162/ft)(21 ft) = 3402
___
<em>Comment on the number</em>
This problem statement doesn't say what the cost units are.
2x-7/2 = 3-6-5x/6
⇒ 2x+ 5x/6= -3+ 7/2
⇒ 2 5/6x= 1/2
⇒ x= (1/2)/ (2 5/6)
⇒ x= 3/17
The final answer is x= 3/17~
<span>a series of logical statement</span>
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.
