Answer:</h2>
The equation that is used to model the length of ladder in terms of x is:
<h2>
Step-by-step explanation:</h2>
We can model this problem with the help of a right angled triangle whose hypotenuse is 13 meters and the other two legs are x meters and (x-7) meters.
where x is the distance between the top of the ladder and the ground.
and (x-7) is the distance between the foot of the ladder and the wall.
Hence, using Pythagorean Theorem we have:
Hence, the answer is:
Given: ax-by>c
Subtract ax on both sides: -by>-ax+c
Divide both sides by -b: y<(-ax+c)/-b
Simplify: y<(ax-c)/b
your answer: y<(ax-c)/b

Answer:
The answer to your question is: 128 days
Step-by-step explanation:
Data
original mass = 21 g
after 45 days = 17.3 g
Process
mass transform = 21 - 17.3 = 3.7 g
21 g ----------------------- 100 %
3.7 g --------------------- x
x = (3.7 x 100) / 21
x = 17.61 %
17.61 % ------------------- 45 days
50% -------------------- x
x = (50 x 45) / 17.61
x = 127.8 ≈ = 128 days
