Introduction to 8th grade math practice learning:
Mathematics is a study of basic math operations and maths functions. Mathematics is one of a language and logic thing of a science. It is an essential tool for science, medicine and the geography fields. In mathematics concept a fundamental concept is arithmetic operations. In 8th grade mathematics includes algebra, number system, measurements, geometry, etc. In this article we shall discuss for 8th grade math practice learning.
I like to share this Square Root Word Problems with you all through my article.
Sample problem for 8th grade math practice learning:
8th grade math practice learning problem 1:
Solve the given algebra sample equation and find out m and n value of the equation.
4m + 6n – 10 = 0
-4m + 18n – 14 = 0
Solution:
We are going to find out the m and n value of the given algebra 1 linear equation.
4m + 6n = 10
-4m + 18n = 14
In the first we are going to add equation (1) and (2). We get
4m + 6n = 10
-4m + 18n = 14
0m + 24n = 24
n = 1
Now, we get the n value as 1. In the equation (2) we substitute n = 1, we get
-4m + 18(1) = 14
-4m + 18 = 14
-4m = -4
M = 1
Now, we get the m value as 1. So, the given system of linear equation values are m = 1, n = 1.
8th grade math practice learning problem 2:
Solve the given algebra equation and find out the ‘p’ value 3 - 2(4p - 5) = 5
Solution:
Given:
3 - 2(4p - 5) = 5
We are going to find ‘p’ value of the given equation. Subtract 3 on both side of the equation, we get
3 - 2(4p - 5) - 3 = 5 - 3
-8p + 10 = 2
In the next step grouping the terms, we get
-8p = 2 - 10
-8p = -8
p = 1
8th grade math practice learning problem 3:
Simplify a given algebraic expression: 4p + 6q - 8 + 5p + 6q + 7.
Solution:
We are going to find a value of the given algebraic expression.
4p and 5p are like terms, and can be combined to give 9p,
6q and 6q combine to give 12q, and
-8 and 7 combine to give -1.
In the next we add all the terms, we get 9p+ 12q - 1.
8th grade math practice learning problem 4:
Find a diameter value from a given circle radius. A given circle radius is 5 cm.
Solution:
Given:
Radius of the circle is r = 5 cm
Diameter of the circle is d = 2r
d = 2 * 5
d = 10
So, the diameter of the circle is 10 cm2.
Practice problem for 8th grade math practice learning:
