Since they are similar you need to start by making ratios for each pentagon.
1.8/2.4 is the first and x/3.6 is the second. Now set them equal to each other and cross multiply.
1.8 X
___ = ____
2.4 3.6
2.4x= 6.48 Now divide both sides by 2.4
2.4x= 6.48
___ ____
2.4 2.4
X= 2.7

Answer:
1 4/9 is the answer
Step-by-step explanation:
converting mixed numbers to fractions, our initial equation becomes,
13/4÷9/4
Applying the fractions formula for division,
=(13×4)/4*9
=52/36
Simplifying 52/36, the answer is
=1 4/9

<u>the correct question is</u>
The denarius was a unit of currency in ancient rome. Suppose it costs the roman government 10 denarii per day to support 4 legionaries and 4 archers. It only costs 5 denarii per day to support 2 legionaries and 2 archers. Use a system of linear equations in two variables. Can we solve for a unique cost for each soldier?
Let
x-------> the cost to support a legionary per day
y-------> the cost to support an archer per day
we know that
4x+4y=10 ---------> equation 1
2x+2y=5 ---------> equation 2
If you multiply equation 1 by 2
2*(2x+2y)=2*5-----------> 4x+4y=10
so
equation 1 and equation 2 are the same
The system has infinite solutions-------> Is a consistent dependent system
therefore
<u>the answer is</u>
We cannot solve for a unique cost for each soldier, because there are infinite solutions.
