Answer:
81 square inches.
Step-by-step explanation:
Draw a diagram to represent what you know.
You don't know the values of the lengths so represent them algebraically.
You know the perimeter is 45 inches and that the perimeter is calculated by the sum of all of the sides of a shape.
You can rearrange to find the value of a side you've denoted as some unknown variable.
The area is given by the product of the sides. Express this algebraically and then input the value you found.
Answer:
Step-by-step explanation:
A value that is 9.75 less than p can be represented by the expression ...
p - 9.75
We are told that value is equal to 64, so the equation is ...
64 = p - 9.75
__
This equation is solved by adding 9.75 to both sides.
64 +9.75 = p -9.75 +9.75
73.75 = p
The store price is $73.75.
Some of the rates that can be formed are; Speed = 8.333 mph
Number of miles covered per gallon of gasoline used = 14.706 mpg
The number of gallons used per hour = 0.567 gallons per hour
<h3>How to use units conversion?</h3>
We are told that the Northwest Football team drove 25 miles.
Now, the time that this team took was 3 hours.
Thus, one rate that can be formed is the speed in mi/hr. Thus;
Speed = 25/3 = 8.333 mph
Another rate that can be found is the number of miles covered per gallon of gasoline used. This gives us;
25/1.7 = 14.706 mpg
Another rate that can be gotten is the number of gallons used per hour;
= 1.7/3 = 0.567 gallons per hour
