Question

an airline allows each passenger 30 kilograms of luggage. Carl has to lower the weight of his suit case by 25% to stay within the limit.

Answer 1

Let 'x' be the original weight of Carl's luggage
Since he needs to lower it by 25% to get to the limit which is 30 kg then you'll have it as:
x - 0.25x = 30kg
-----------------
Using the equation, find x

Answer 2

how much did the suitcase originally weigh?

Answer 3

Let M be the maximum weight allowed, and W be the original weight. We know that Carl had to remove 25% of W to make his suitcase's weight be M, and we know that M is 36 kg.

(W-25% of W) = M = 36 kg

But 25% is just 25/100, so we can write
\[W - \left(\begin{matrix}25 \\ 100\end{matrix}\right) W = 36 kg\]
multiply both sides by 100 to get rid of the fraction
\[100W -25W = 3600kg\]
\[75W = 3600kg\]
Divide both sides by 75 to find W

Answer 4

100 * ? = 4800
25 * ? = 1200
4800 - 1200 = 3600
So what is the ?

Answer 5

48?

Answer 6

i dont get it -_-

Answer 7

Correct

Answer 8

i type in 48 and it said it was wrong

Answer 9

@I_Need_Help_With_Home it's actually 30kg in the given

Answer 10

get the value of x in the above equation @jayybee7

Answer 11

so whats the answer?

Answer 12

i tried.. I give up..

Answer 13

x - 0.25x = 30kg

Answer 14

I dont no how

Answer 15

x - 0.25x = 30kg
Simplify
0.75x = 30kg
Divide both sides of the equation by 0.75
x = 30/0.75
x = ?

Answer 16

I still dont get it.. I find it very difficult and frustarting..

Answer 17

40?

Answer 18

If we let 'x' be the original weight of Carl's luggage and he has to deduct 25% of it to reach the limit which is 30kg, then we can say that what's left is just 75% of the original weight
75% x = 30
changing 75% to decimal you'll have it as 0.75
0.75x = 30
x = 30/0.75
x = 40kg
