The answer is d + 0.25(d - 22) = 10.75
d - the amount of dollar coins
q - the amount of quarters
It is given: d + q = 22
The quarter is $0.25, therefore:
d + 0.25q = 10.75
Now, we have the system of equations:
d + q = 22
d + 0.25q = 10.75
According to the first equation:
d + q = 22 <span>⇒ q = 22 - d</span>
We will replace q in the second equation:
d + 0.25q = 10.75 ⇒ d + 0.25(22 - d) = 10.75
Let the number of hotdogs sold = X
Soda was 2 times the amount so soda = 2x
The total of both was 225:
2X + x = 225
Simplify:
3x = 225
Divide both sides by 3:
x = 225/3
x = 75
Hot dogs = 75
Soda = (75 x 2) = 150
Answer: Yes it is possible to design more than one flag with these lengths because the two smaller side lengths 27 and 40 is greater than 50 which is the larger side length.
Step-by-step explanation:
Mean is 750 and mode is 850
