Students can schedule their online sessions as per their convenience and solve all Math problems constantly. Math needs constant practice and hence, students should practice Math worksheets on a regular basis. While solving Math worksheets, students may face many problems and to solve these problems precisely, they can choose online sessions with expert Math tutors. In this session, they can understand each problem in a step-by-step manner. Students can opt for sessions to solve various Math problems of Grade 8. Each of these sessions is guided under the supervision of subject experts and therefore, is recommended for students.

Solved Examples

Question 1: Determine the value of y when x = 9 given y = $\sqrt{9x}$ + 2x.

Given, y = $\sqrt{9x}$ + 2x

Put x = 9

$\Rightarrow$ y = $\sqrt{9 \times 9}$ + 2 $\times$ 9

$\Rightarrow$ y = $\sqrt{9^2}$ + 18

$\Rightarrow$ y = 9 + 18

$\Rightarrow$ y = 27

Question 2: Express the 72 as product of prime factors.
Number = 72

Prime factors of 72

72 = 2 $\times$ 2 $\times$ 2 $\times$ 3 $\times$ 3


Question 3: Subtract $2\frac{3}{5}$ - $1\frac{3}{5}$
Convert mixed fractions into improper fractions

$2\frac{3}{5}$ = $\frac{13}{5}$

and $1\frac{3}{5}$ = $\frac{8}{5}$

$\Rightarrow$ $\frac{13}{5}$ - $\frac{8}{5}$ = $\frac{13 - 8}{5}$

= $\frac{5}{5}$

= 1

$\Rightarrow$ $2\frac{3}{5}$ - $1\frac{3}{5}$ = 1

Question 4: The sum of two numbers is 13. If two times one of these numbers exceeds three times the other number by 1, find the numbers.
Let the numbers be x and y

The sum of numbers = 13

$\Rightarrow$ x + y = 13                 ...............(1)
2x - 3y = 1                    .................(2)

Step 2:

(1) => y = 13 - x

Step 3:

Put y = 13 - x in equation (2)

$\Rightarrow$ 2x - 3(13 - x) = 1

$\Rightarrow$ 2x - 39 + 3x = 1

$\Rightarrow$ 5x = 40

$\Rightarrow$ x = 8

Step 4:
Put x = 8 in equation(1)

$\Rightarrow$ 8 + y = 13

$\Rightarrow$ y = 13 - 8 = 5

Hence numbers are 8 and 5.
