PLEASE HELP I believe you have to use substitution or elimination to solve the problem.
zepelin [54]

<u>Answer:</u>

Amount collected in 2012 = 3.49

and in 2013 = 3.35

<u>Explanation:</u>

Let x be the baggage fees collected in 2013 and

y be the baggage fees collected by airlines in 2012

From the given question we can obtain two equations as follows:

x + y = 6.84 $   - eq 1

and

y = 0.14 + x

as fees in 2012 exceeds that in 2013 by 0.14$

Now, solving these two equations by substitution,

we substitute  y = 0.14 + x in eq 1

and solve for x,

which gives us x = 3.35 and

substituting this value in eq 1

we get y = 3.49

The top of a desk is shaped like a trapezoid. The bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk
Stolb23 [73]

Answer:

28 centimeters.

Step-by-step explanation:    

Let w be width of desk.

We have been given that the bases of the trapezoid are 26.5 and 30 centimeters long. The area of the desk is 791 square centimeters long.

Since the area of trapezoid is half the sum of parallel sides times its height.

\text{Area of trapezoid}=\frac{h}{2}*(a+b), where

h= Height of trapezoid,

a and b= Length of parallel sides of trapezoid.

We have been given that the height of the trapezoid is the width of the desk.

Upon substituting our given vales in above formula we will get,

791=\frac{w}{2}*(26.5+30)

791=\frac{w}{2}*(56.5)

791=w*28.25

w=\frac{791}{28.25}

w=28

Therefore, the width of trapezoid is 28 centimeters.
