Answer Math Questions For Me

Introduction to answer math questions for me:

Answering math questions is a simple one. The math terms for whom it is well known can answer the math questions. The math question involves the various topics in which the each topic can be solved through the different manner. The math questions may have the various methods for the solving purpose but the solution of the question may be the same in whatever method the particular problem is made to solve. I like to share this Solve Fractional Equations with you all through my article.


Answer math questions for me:


The answer math questions are done through the well trained persons who have the certificates under the math. The math can be taught under various methods, it is better to solve in the known steps and also preferring the easy steps for solving the questions. The math questions should be read more than one times to have the cute understandings on the particular topics. These math answers would helps you to have the quite understanding on the methods mentioned below.

Understanding Dividing Fractions Calculator is always challenging for me but thanks to all math help websites to help me out.

Examples for math questions for me:


Example 1:

What is -6+ (-2)?

From above: (- )+(-) becomes a negative sign.

-6+ (-2) = -6 - 2

Answer: -6+ (-2) = -8.

Example 2 : What is -5+ (-2)?

+ (-) gives a negative sign.

-5+ (-2) = -5 - 2 = -7.

Answer: -5+ (-2) = -7.

Example 3: What is -6- (+3)?

- (+) becomes a negative sign.

-6- (+3) = -6 - 3=-9

Example 4: solve 1/3 + 2/6 fraction problem:

=   1/3 + 2/6

Having common denominator has 6 then multiply 3 with 2 then we can have 6 has the common denominator. so multiply 2 with 3 then it becomes 6.

=   2/6 + 2/6

=   4/6

Answer :  2/3.

Example 5: Solve 2/4 + 1/4 fraction problem:

= 2/4 + 1/4

Having common denominator has 4 simply add the numerators  = (2 + 1)/4

= 3/4

Answer: 3/4.

Example 6: Solve 12/5 + 5/6

= 12/5 + 5/6

= [(12 X 6) + (5 X 5)]/ 30

= [72 + 25]/30

= 97/30

Answer: 97/30

Example 7: solve 8/7 + 5/4

= [(8X 4) + (5 X 7)]/4 X 7

= [(32) + (35)]/28

= 67/28

Answer: 67/28

Example 8:

Heights in cms of ten people are:

126, 145, 150, 157, 149, 136, 166, 129, 143, 134

Solution:

Mean: sum of all values/total numbers

Mean= 1435/10

=143.5

Answer: 143.5

Example 9:

The highest scores of the five players in twenty twenty are:

198,192,182,190,179.

Solution:

Mean = sum of all values/total numbers.

= 941/5

Answer: 188.2

Example 10:

Heights in cms of thirteen players are:

110,115,120,125,130,135,150,145,150,155.

Solution:

Mean: sum of all values/total numbers

Mean = 1335/10

= 133.5

Answer: 133.307

Example 11:

The highest scores of the ten players one day are:

198,195,192,190,186,194,182,180,179,178.

Solution:

Mean = sum of all values/total numbers.

= 1874/10

Answer: 187.4

Answer Math Question Now

Introduction to mathematics:

Mathematics is the study of quantity, structure, space, and change. Mathematicians seek out patterns, formulate new conjectures, and establish truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics is used throughout the world as an essential tool in many fields, including natural science, engineering, and medicine. (Source: From Wikipedia). Now, we are going to see some of the question and answer in mathematics. I like to share this What are Variables? with you all through my article.


Math questions and answers:

Example question 1:

Solve for the variable x: 2x + 3 = 5

Solution:

2x + 3 = 5

Subtract 3 on both sides of the equation

2x + 3 – 3 = 5 – 3

2x = 2

Now, divide by 2 on both sides of the equation

2x / 2 = 2 / 2

x = 1

So, the answer is x=1.

Example question 2:

Find the value of the expression: xy+2x+3yz when x=1, y=0 and z=2.

Solution:

xy + 2x + 3yz

Now, substitute the value of x, y and z in the expression

xy + 2x + 3yz = 1(0) + 2(1) + 3(0)(2)

= 0 + 2 + 0

= 2

So, the answer is 2.

Understanding Pythagoras Theorem is always challenging for me but thanks to all math help websites to help me out.

Additional questions and answers in maths:


Example question 3:

The perimeter of the floor of a rectangular hall is 26 m. Its length is 8 m. Find its area.

Solution:

To determine the area we should know the length and breadth of a rectangle. So, we should find the breadth from the perimeter.

2 length + 2 breadth = perimeter

2 × 8 + 2b = 26

16 + 2b = 26

i.e. 2b = 26 – 16

2b = 10

b =10 / 2 = 5

Now the area of the rectangle A = l b

= 8 m × 5 m

= 40 sq.m.

So, the answer is 40 square meter.

Example question 3:

In a right triangle the length of the base is20 cm and the height is 25 cm. Find its area.

Solution:

Let b = 20 cm and h = 25 cm

Now, we know the formula,

Area of the right triangle, A = (1 / 2)*b*h

= (1 / 2) × 20 cm × 25 cm

= 250  sq.cm

So, the answer is 250 square cm.

Example question 5:

The mean marks in mathematics for a class is 42. If there are 50 pupils in the class find the total marks scored by them in mathematics.

Solution:

Total marks / number of pupils = mean

Total marks = mean × number of pupils

= 42 × 50

= 2100.

So, the answer is 2100 marks.
