<h3>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

An elevator travels 310 ft in 10 seconds at that speed how far can this elevator travel in 12 seconds explain your reasoning
marta [7]

Answer:

<u>372 ft</u>

Step-by-step explanation:

This can be solved through cross multiplication.

310ft/10sec= x/12sec

Multiply the values across from each other. (A good way to know you've done it properly is if the numbers you multiplied are in different measurements. ex: 1 value is feet,  the other is seconds)

310 x 12 = 3720

Divide by the remaining value.

3720 / 10 = 372
