Step-by-step explanation:
Given that the 2 triangles are similar then the ratios of corresponding sides are equal.
This enables RT to be found, that is
=
( cross- multiply )
4RT = 60 ( divide both sides by 4 )
RT = 15
Hence
perimeter of ΔRST = 6 + 12 + 15 = 33 units

The graph in the attached figure
Step-by-step explanation:
Let
x----> the number of boys
y----> the number of girls
we know that
-----> equation A
----> equation B
Solve the system of equations by graphing
Remember that the solution of the system of equations is the intersection point both graphs
The solution is the point (8,16)
see the attached figure
therefore
There are 8 boys in the chorus
There are 16 girls in the chorus
