Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer

Answer:
Among the given statements the one which describes the properties of
Δ ABC and Δ A"B"C" is,
∠C and ∠C" are congruent after both the translation and dilation.
Step-by-step explanation:
Δ ABC is translated by the rule (x +1, y +1) and then dilated by a scale factor of 2 centered at the origin and the new triangle which we get is named as Δ A"B"C" .
Now, among the given statements the one which describes the properties of
Δ ABC and Δ A"B"C" is,
∠C and ∠C" are congruent after both the translation and dilation.
