Answer:
4/990
Step-by-step explanation:
let 0.04 be x
so 100x is 4.04
so subtract x from 100x
you get 99x which is 4
if 99x is 4
then x is 4/99
=4/99
(21x-3x)+9
Answer is 18x+9

Answer:
shortest side = 15
Step-by-step explanation:
The question is a bit ambiguous. Do you mean (3/4) x or do you mean 3/(4x)?
I'll take it to be the first one.
(x + 3) + 4(x - 13) + (3/4)x = 3x + 6 Remove the brackets on the left
x + 3 + 4x - 52 + 0.75 x = 3x + 6 Combine
5.75x - 49 = 3x + 6 Subtract 3x from both sides.
2.75x - 49 = 6 Add 49 to both sides
2.75x = 55 Divide by 2.75
x = 55/ 2.75
x = 20
Now for the shortest side
x + 3 = 23
4(x - 13) = 4(20 - 13) = 4*7 = 28
(3/4)*20 = 15
The shortest side = 15
