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

Step-by-step explanation:
Hello !
(4,4*2,4) + (3,14 * 2,2² )/2 =
10,56 + 7,60 = 18,2 m²
Part A is correct!
Part B is Interquartile Range:3
Part C is 0 and 8
I hope I helped you!♥
Step-by-step explanation:
6) x+y=60
x/y=7/5------(2)
x=(7/5)y
(7/5)y + y =60
(12/5)y=60
y=60(5/12)
y= 25
x=(7/5)y=(7/5)×25 =35
the two numbers are 35 and 25
7)distance walked by A = 4t
distance walked by B = 5t
4t+5t=27
9t=27
t=27/9=3hours
