Ok here is how you do this:
you need to replace y with 20 and then solve to find x, i.e. solve this equation
20=2/5x
1. Simplify 2/5x to 2x/5
20=2x/5
2. Multiply both sides by 5
20 * 5=2x
3. Simplify 20 * 5 to 100
100=2x
4. Divide both sides by 2
100/2=x
5. Simplify 100/2 to 50
50=x
6. Switch sides
x=50
so your answer is B. 50
I hope this helped!

2s + 100 when s=80 the latest balance of Ahmed's savings is $260
because he doubles his savings you times s by two and then add 100 because he deposited this after.
Answer:
we have x=1, y=0 and x=-3, y=4
Step-by-step explanation:
We need to solve the equations: 
Let:
Putting value of eq(2) into eq(1)
Now finding values of y for x=1 and x=-3
So, we have x=1, y=0 and x=-3, y=4
The translated function is given by:
g(x) = 3|x + 1| - 3.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the parent function is given by:
f(x) = |x + 1| - 1.
For a vertical stretch by a factor of 3, the function is multiplied by 3, hence the translated function is given by:
g(x) = 3f(x) = 3(|x + 1| - 1) = 3|x + 1| - 3.
