Answer: 
Step-by-step explanation:
Given
The ratio of the area of the similar triangles is equal to the square of the side of the corresponding sides
Suppose the corresponding side on figure A is 
On solving
![\Rightarrow \dfrac{16}{49}=[\dfrac{x}{5}]^2\\\\\Rightarrow \dfrac{x}{5}=\sqrt{\dfrac{16}{49}}\\\\\Rightarrow \dfrac{x}{5}=\dfrac{4}{7}\\\\\Rightarrow x=\dfrac{20}{7}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cdfrac%7B16%7D%7B49%7D%3D%5B%5Cdfrac%7Bx%7D%7B5%7D%5D%5E2%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7Bx%7D%7B5%7D%3D%5Csqrt%7B%5Cdfrac%7B16%7D%7B49%7D%7D%5C%5C%5C%5C%5CRightarrow%20%5Cdfrac%7Bx%7D%7B5%7D%3D%5Cdfrac%7B4%7D%7B7%7D%5C%5C%5C%5C%5CRightarrow%20x%3D%5Cdfrac%7B20%7D%7B7%7D)

Answer:
the answer would be 15x+ 1
Step-by-step explanation:
The number of half dollars coins are 5 and the number of the quarters dollars coins are 12.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You have a cup with 17 coins inside.
The total inside the cup is $5.50.
Let x be the number of half dollars and y be the number of the quarters dollars.
Then the equations will be
x + y = 17 ............1
0.5x + 0.25y = 5.5 ...........2
By solving equations 1 and 2, we have
x = 5 and y = 12
