The total perimeter of the school crossing sign measures 102 inches.
To find the length of each side, knowing the number of sides is necessary.
If it has 5 sides, dividing 102 by 5 results in 20.4 inches per side.
If it has 4 sides, dividing 102 by 4 gives a side length of 25.5 inches.
So, the side length depends on how many sides the sign has.
Given :
Miki possesses 104 nickels and 88 dimes. She intends to sort her coins into sets where each set has an equal count of both nickels and dimes.
Last year, 216,000 cars were sold.
To Find :
An equation that can identify the number of trucks, t, sold the previous year.
Solution :
Let t represent the quantity of trucks sold and c represent the cars sold.
The statement indicates that the quantity of cars sold exceeded three times the trucks sold by 39,000.
Thus,

Plugging the value of c = 216000 into the equation above yields :

This gives us the solution we seek.
Response: It will require him 1 hour and 35 minutes
The total distance separating them is 0.25 + 0.75 = 1 mile
So, when will Amir travel 1 mile more than Sal?
Keep in mind that distance = speed multiplied by time
When will Sal's distance + 1 equal Amir's distance?
d = st
where h = time in hours
4.5h + 1 = 6.7h
Now, let's isolate h
Subtract 4.5h from both sides
1 = 2.2h
Dividing each side by 2.2 gives us
0.454545 = h
rounded to the nearest hundredth is
0.45 hours
