Let Q = quarters and D = dimes
There are a total of 1202 coins, so we have to add the quarters and dimes together to get this.
Q + D = 1202
Quarters have a value of 25 cents or 0.25, dimes have a value of 10 cents or 0.10. The combination of the amount of quarters and their respective value and the amount of dimes and their respective value equate to $123.50.
0.25Q + 0.10D = 123.50
Put the two equations together. Your system of equations is:
Q + D = 1202
0.25Q + 0.10D = 123.50
The question is incomplete as the total number I crosswords required for completion isn't given :
Hypothetically, if the total Number of cross words is taken as x ;
Answer:
2 /x
Step-by-step explanation:
The number of crosswords John did = 1 + 1 = 2
Total number of cross words = x
Fraction of crosswords John did :
2 / total number of crosswords
2 / x
Kindly substitute the actual number of crosswords for X to obtain exact answer.

Step-by-step explanation:
Answer: The company currently has 17 employees
Step-by-step explanation:
Let X represent the number of current employees in the company
From the first information, it can be expressed mathematically as
X + 3 ≥ 20
X ≥ 20 - 3
X ≥ 17
From the second information, it can be expressed mathematically as
X - 3 < 15
X < 15 + 3
X < 18
From the above solutions, it can be deduced that
17 ≤ X < 18
The only number that fulfils this criteria is 17.
Therefore, X = 17
