The two numbers it lies between are 4 and 5
So we are trying to solve for x so in order to do that we need to get x by itself on one side of the equal sign
first we are going to combine like terms on each side of the equal side
so on the left side we see 4+9 these are booth whole numbers not attached to a variable so we can simplify this by adding these two values together making our equation: x/13 = 12
our x is still not by itself so in order to get it by itself we need to get rid of that 13
we need that x is being divided by 13 so in order to get rid a divided value we have to do the opposite to both sides - multiply by 13 on each side!
x/13 x 13 = x
12 x 13 = 156
so our equation is now:
x = 156
is our x by itself on one side of the equal sign? yes! so our x value is 156

Answer:
An equation that indicates you can spend exactly $45 per day for rental fees is, 
Step-by-step explanation:
Let x represents the days and y represents total the rental fees.
As per the statement:
you can spend exactly $45 per day for rental fees.
In 1 day you spend = $45 rental fees.
then
in x days = 45 x
we have to find an equation that indicates you can spend exactly $45 per day for rental fees
since, y represents the total rental fees,.
⇒ y= 45x
Therefore, an equation that indicates you can spend exactly $45 per day for rental fees is, 
Can it be a decimal? Only one I can think of is 1 X 31
