Let the additional fee , the shipping company charges be $y .
So for 0.75 pounds, since the weight is less then 1 pound, company charge = $2x
For 3 packages with weigh 2.5 pounds, company charge 3* ( x+(2.5-1)*y )
= 3x+4.5y
For package with weighs 4.2 pounds, company charge x+(4.2-1)y = x+3.1y
So the total amount , company charge = 2x +3x +4.5y +x+3.1y
=6x +7.6y
Answer:
12 1/2
Step-by-step explanation:
(((x + y) / 3) + (1 / x)) / (5 + (15 / x))
The best way is to make it one fraction.
Multiply by ((3x/3x) / (3x/3x)) to remove the other fractions.
((x(x + y)) + 3(1)) / (5(3x) + 3(15))
(x^2 + xy + 3) / (15x + 45)
Then factor to simplify
(x^2 + xy + 3) / (3(x + 15))
Hey!
Okay, to solve this problem, we'd first have to multiply both sides by two. The reason we do this is to get

on its own.
<em>Original Equation : </em>

<
<em>New Equation {Changed by Multiplying 2 on Both Sides} :</em>

<

(

)
And we simplify the equation to get our answer.
<em>Old Equation :</em>

<

(

)
<em>New Equation {Changed by Simplification} :</em>
y < -6
<em>So, the equation

< -3 simplified is</em>
y < -6.
Hope this helps!
