I have a very expert technique that is very easy to changed decimal into mixed fraction
All you have to do is nevermind of the integer sign
So we will move on to 30.75
The first is write it in word so 30.75 is thirty and seventy five hundreths
Then analyze so 30 is the whole number and 75 is numerator then 100 is the denominator
So it is 30 75/100 then simplify it to the lowest terms
= 123/4 or 30 3/5
There are 28 right handed students in class
<em><u>Solution:</u></em>
Given that, there are 32 students in a class
The ratio of left-handed students to right- handed students is 1 : 7
Let the number of left handed students be 1x
Let the number of right handed students be 7x
<em><u>To find: Number of right handed students in school</u></em>
Total number of students = 32
number of left handed students + number of right handed students = 32
1x + 7x = 32
8x = 32
x = 4
number of right handed students = 7x = 7(4) = 28
There there are 28 right handed students in class
Function: In the graph of a continuous function, the points are connected with a continuous line, since every point has meaning to the original problem. Function: In the graph of a discrete function, only separate, distinct points are plotted, and only these points have meaning to the original problem
Answer:
20
Step-by-step explanation:
we can set up the equation like this:
n/4 + 2 = 7
subtract 2 from both sides
n/4 = 5
multiply 4 to both sides and you get...
n = 20
Answer: OPTION B.
Step-by-step explanation:
Given the following System of equations:
You can use the Elimination Method to solve it. The steps are:
1. You can mutliply the second equation by -3.
2. Then you must add the equations.
3. Solve for the variable "y".
Then:
4. Now that you know the value of the variable "y", you must substitute it into any original equation.
5. The final step is to solve for "x" in order to find its value.
Then:
Therefore, the solution is:
