Any number that can be written in fraction form is a rational number, so numbers like -1/8, 0, 1/4, etc. all work.
Answer:
There were 26 students in his class and the teacher had 83 ml of the solution.
Step-by-step explanation:
Mr. Kohl has a "x" amount of solution, if he divides it by the number of students "n" he'll give each student 3 milliliters and have a left over of 5 milliliters. If the amount of solution Mr. Kohl had was "x + 21" then he'd be able to give each student 4 milliliters of the solution. From these informations we have:
x = 3*n + 5
(x + 21)/n = 4
x + 21 = 4*n
x = 4*n - 21
Now that we have two equations and two variables we can solve the system of equations, as seen bellow:
3*n + 5 = 4*n - 21
3*n - 4*n = -21 - 5
-n = -26
n = 26
x = 4*26 - 21 = 83 ml
There were 26 students in his class and the teacher had 83 ml of the solution.
Answer:
4 4/2
Step-by-step explanation:
What you do is you have to do 8-4=4 5-1=4 6-4=2 so there for the answer is 4 4/2
Point-slope form of equation is:
Step-by-step explanation:
Given points are:
(2,-8) and (1,7)
First of all we have to calculate the slope of the line
so,
Point-slope form is given by:
Putting the value of slope
We can put any one of two given points in the equation to find the final form of point-slope form
So
Putting (1,7) in the equation
Hence, point-slope form of equation is:
Reducing and simplifying
