8th grade math problems

In this blog we will learn about 8th grade math problems,we can see one example problem of 8th grade math problems given below:
Solve: 16(s – 4) – 26s - 21 = 9(s + 8)

Solution:

Given expression is,

16(s – 4) – 26s - 21 = 9(s + 8)

Multiplying the integer terms

16s - 64 – 26s - 21 = 9s + 72

Grouping the above terms

-10s - 85 = 9s + 72

Add 8 on both sides

-10s + 85 – 85 = 9s + 72 + 85

Grouping the above terms

-10s = 9s + 157

Subtract 9s by on both sides

-10s – 9s = 9s + 157 – 9s

Grouping the above terms

-19s = 157

Divide -4 on both sides

s = -157/19

Answer: s = -157/19.Next we will learn about an grade 6 math probability example.Suppose the rectangle is divided into 4 parts, 2 parts of the rectangle are colored as pink ,one part of the rectangle is divided as blue and the one part is colored as yellow find the probability of the blue region ?

Solution:

Here the rectangle is divided into 4 parts so it is the total number it will be represents in the denominator and only one part is colored as blue region it will be represents in the numerator so the probability of the blue region will be shown as below ,

¼=0.25In the next blog we will learn about standard form,hope you like the example of 8th grade math problems,please leave your comments if you have any doubts.

collinear points

In this blog we will learn about collinear points.Collinear points are the points that lie on the assonant distinction whereas the non-collinear points do not lie on the assonant pipe.The erect blood can ever be haggard finished two points, so the two points are always collinear.A credit, on which points lie, specifically if it is akin to a geometric amount much as a triangle, is sometimes titled an alinement.We can use interval expression to chance out whether the relinquished ternary points are collinear or not.We will now see one example of square inch calculator,

1. Convert the area of 2.2 sq yards into square inches using calculator.

Solution:

1 square yard = 1296 square inches.

2.2 square yard = 2.2 *1296 square inches

2.2 square yard = 2851.2 square inches

2. Find the area of 3 square foot in terms of square inches.

Solution:

1 square inch = 0.006944 square foot.

1 square foot = square inches

3 square foot = square inches.

= 432 square inches.

3. convert the area of 25 square centimeters into square inches.In the next blog we will learn about statistics.Hope you like the above example of collinear points,please leave your comments if you have any doubts.

examples of probability

In this blog we will learn about examples of probability,we can one one example of probability given below.

If there are 6 apples, 3 oranges, and 1 banana in a basket, what is the probability of choosing an apple without looking in the basket?

Solution for example of probability:

P(choosing an apple)= 6/10 = 3/5 = 0.6 = 60%

The numerator is 6 because there are 6 apples in the basket, therefore six outcomes. the total number of outcomes = 10.Next we will learn about dividing polynomials calculator,we can see one example here:

Solve divide polynomial

Solution:-

Given :

= -

=

Explanation:-

First to separate the equation by denominator then divide both sides equation. Finally we got an answer as .In the blog we will learn about area of circle.Hope you like the above example of examples of probability,please leave your comments if you have any doubts.
