Need pre algebra tutor
Introduction :
Pre algebra is a common name for a course in middle school mathematics. In the United States, it is generally taught between the seventh and ninth grades. The objective of pre algebra is to prepare the student for the study of algebra.
Many students need help with pre algebra while doing homework or preparing for exam. In online, many highly qualified tutors are available to help the students if they need help in pre algebra. Online tutors clear their doubts with a clear explanation. Students can get help from anywhere around the world with tutors.
Pre algebra - Percent problems:
A few example problems are given below for the students who need help with percent problems from pre algebra tutor.
Example problem 1:
In a class, 40 students took a geometry test. If 30 students passed the geometry test, find out what percent do not pass the test?
Solution:
First, we have to find how many students did not pass the test.
Number of students did not pass the test = 40 - 30 = 10
Then, we have the equation.
x% of 40 = 10
Divide by 10 on both sides,
x% = 0.25
x = 0.25*100
x = 25%
Therefore, 25% of students did not pass the test.
Example problem 2:
In a test, there are 40 questions totally. If Joseph gets 60% correct answers, how many questions did Joseph gets the wrong answer?
Solution:
First, we have to calculate the number of correct answers.
Number of correct answers = 60% of 40
= `60/100` * 40
= 0.6 * 40
= 24
So, he got 24 correct answers.
Therefore,
Number of wrong answers = 40 - 24
= 16
Hence, Joseph got 16 wrong answers.
Pre algebra - Expressions and Equations
A few example problems are given below for the students who need help with expressions and equations from pre algebra tutor.
Example problem 1:
Evaluate the expression 6n + 3 when n = 4.
Solution:
Step 1: Given expression
6n + 3
Step 2: Plug n = 4 in the given expression 6n + 3 and solve for n
6n + 3 = 6(4) + 3
6n + 3 = 24 + 3
6n + 3 = 27
Step 3: Solution
When n = 4, 6n + 3 = 27
Example problem 2:
Solve the equation `4/5` x + 4 = 8
Solution:
Step 1: Given equation
`4/5` x + 4 = 8
Step 2: Subtract 4 on both side of the equation `4/5` x + 4 = 8 to move the constant 4 to right side of the equation
`4/5` x + 4 - 4 = 8 - 4
`4/5` x = 4
Step 3: Multiply by 5 on both sides
4x = 20
Step 4: Divide by 4 on both sides
x = 5
