22903.	The sum of two consecutive odd numbers is 56Find another numbers
Answer» Answer: 27 & 29 Step-by-step explanation: Let x and x + 2 be the TWO CONSECUTIVE odd numbers. According to the question, we have : x + (x + 2) = 56 ⇒x + x + 2 = 56 ⇒2x + 2 = 56 ⇒2x = 56 - 2 ⇒x = 54/2 ⇒x = 27 Finding the numbers : x = 27 x + 2 = 27 + 2 = 29 Hence, the two consecutive odd numbers whose sum is 56 are 27 and 29.

22903.

The sum of two consecutive odd numbers is 56Find another numbers

Answer»

Answer:

27 & 29

Step-by-step explanation:

Let x and x + 2 be the TWO CONSECUTIVE odd numbers.

According to the question, we have :

x + (x + 2) = 56

⇒x + x + 2 = 56

⇒2x + 2 = 56

⇒2x = 56 - 2

⇒x = 54/2

⇒x = 27

Finding the numbers :

x = 27

x + 2 = 27 + 2 = 29

Hence, the two consecutive odd numbers whose sum is 56 are 27 and 29.

Answer» Answer: value of y when x=0 is y=4 solution of the EQUATION 4x+y=7 are x=0, y=7 and x=1, y=3 Step-by-step EXPLANATION: To find the value of y when x=0, put x=0 in the equation 4x+5y=20 => 4*0+5y=20 => 5y=20 => y=20/5 =4 => y=4 To find any two solution of the equation 4x+y=7 first put any value CORRESPONDING to x and substitute in the equation just like the above method, you will get the corresponding value of y. It will be ome of the solution of that equation. similarly take any other value of x and you will get the second pair of the solution.

4x+5y=20 find the value of y when x =0 in this equation write any two solution of the equation 4x +y=7

Answer»

Answer:

value of y when x=0 is y=4

solution of the EQUATION 4x+y=7 are x=0, y=7

and x=1, y=3

Step-by-step EXPLANATION:

To find the value of y when x=0, put x=0 in the equation 4x+5y=20

=> 4*0+5y=20

=> 5y=20

=> y=20/5 =4

=> y=4

To find any two solution of the equation 4x+y=7

first put any value CORRESPONDING to x and substitute in the equation just like the above method, you will get the corresponding value of y.

It will be ome of the solution of that equation.

similarly take any other value of x and you will get the second pair of the solution.

22949.	A person starts from a point P and walks 1 kmalong a straight line and then turns to hisright and walks straight for 2 km. After that,he turns to his left and walks for 3 km toreach a point Q. What is the straight linedistance of the point Q from the point P ?
Answer» Answer: Correct option is B 15 km The movement of the PERSON are as shown in fig. Clearly AB = 3 km BC=3AB=(3×3)KM=9KM CD=5AB=(5×3)KM=15KM Draw AE ⊥ CD. Then CE = AB = 3 km and AE = BC = 9Km DE = (CD-CE)=(15-3)Km = 12 Km. In Δ AED, AD 2 =AE 2 +DE 2 = AD=( 9 2 +(12) 2 )km=15km ∴ Required distance = AD = 15 Km.

A person starts from a point P and walks 1 kmalong a straight line and then turns to hisright and walks straight for 2 km. After that,he turns to his left and walks for 3 km toreach a point Q. What is the straight linedistance of the point Q from the point P ?

Answer»

Answer:

Correct option is

B

15 km

The movement of the PERSON are as shown in fig.

Clearly AB = 3 km

BC=3AB=(3×3)KM=9KM

CD=5AB=(5×3)KM=15KM

Draw AE ⊥ CD.

Then CE = AB = 3 km and

AE = BC = 9Km

DE = (CD-CE)=(15-3)Km = 12 Km.

In Δ AED, AD
