80 students took an algebra exam and 75 past it in simplest form what fraction of students did not pass the exam

1/16

Step-by-step explanation:

75 of the 80 pass

80-75 = 5

That means 5 did not pass

Fraction that did not pass = people that did not pass/ total

                                           = 5/80

divide the top and bottom by 5

                                            =1/ 16

1/16

Step-by-step explanation:

That's a pretty good class average. Only 5 people didn't pass the exam, which we can get by subtracting 75 from 80.

Now, we can write it as a fraction. This is how well represent it in its simplest form.

If 5 out of 80 passed the exam, we could write it as 5/80. To simplify it as much as we can, We would want to turn 5 into 1, if thats possible for the other number without it turning into a decimal.

To turn 5 into 1, we can divide 5 by 5. Since we divided the numerator by 5, we have to divide the denominator by 5.

80/5=16

Put our answers as a fraction.

The simplest form is 1/16

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
