What is the value of P in the following Equation ? 192.5 × 19p = 197

Correct Answer: 50

Explanation:

Given 7 + 7/7 + 7 x 7 - 7

By using BODMAS rule,

7 + 1 + 7 x 7 - 7

= 8 + 49 - 7

= 57 - 7

= 50.

 

Hence 7 + 7/7 + 7 x 7 - 7 = 50.

Correct Answer: 548

Explanation:

? = 5068 x 4/37

? = 548

Correct Answer: 12

Explanation:

Using BODMAS law,

3 x 3 + 3 - 3 + 3 =

3 x 3 = 12

= 12 + 3 - 3 + 3

=  9 + 3

= 12

 

Hence, 3 x 3 + 3 - 3 + 3 = 12.

Correct Answer: 112

Explanation:

$$\begin{gathered} 7 + 7 ÷ 7 + 7 x 7 + 7 - 7 ÷ 7 + 7 x 7 \\ = 7 + 1 + 49 + 7 - 1 + 49 \\ = 8 + 56 + 48 \\ = 56 + 56 \\ = 112 \end{gathered}$$

Correct Answer: 89

Explanation:

This can be done in a method called Approximation.

Now, 

$$\begin{gathered} 5 2 + 6 3 + 6 + 7 2 = ? x 3 . 34 \\ 25 + 216 + 6 + 49 = ? x 3 . 34 \\ 296 = ? x 3 . 34 \\ ? = 296 3 . 34 = 88 . 622 ? 89 \end{gathered}$$

Correct Answer: 2X^2

Explanation:

Here the given expression, 

X 2 + X 2 is an algebraic expression. Here in this expression the terms are like terms. Now to add them, add their coefficients.

Here in the given expression, the like terms are two  X 2

Hence, adding their coefficients i.e, 1 + 1 = 2

Therefore, 

 

X 2 + X 2 = 2 X 2.

Correct Answer: -1

Explanation:

Given 5x - 6 = 3x - 8

5x - 3x = -8 + 6

2x = -2

=> x = -1.

Correct Answer: 3/8

Explanation:

Now to find the difference in the given fractions, 1/2 - 1/8

First take the LCM of 2 & 8

LCM of 2 & 8 is 8

Then,

1/2 - 1/8

= (4 - 1)/8

= 3/8

 

Hence, 1/2 - 1/8 = 3/8.
