The value of x if x/80-x = 3/5 is
a. 120
b, 60
c. 30
d. 40

c

Step-by-step explanation:

We can multiply each side by (80-x) to get:

x = 3/5 · 80 -x

x = 60-x

Move -x to the other side:

2x = 60

Then divide both sides by 2:

x = 30

So, your answer is c. 30

step-by-step explanation:

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
