Hi ,

This word problem related to linear equations in one varibles.
Read the problem carefully and convert it into linear equation.

Let the number = x

1 / 3 RD of the number = x / 3

2 / 7 of the number = 2x / 7

Relation given is ,

1 / 3 of the number exceeds its 2 / 7 by 1.

x / 3 - 2x / 7 = 1

L C M of 3 and 7 = 3 × 7 = 21

( 7x - 6x ) / 21 = 1

x / 21 = 1

Multiply both sides with 21 we get

21 × x / 21 = 1 × 21

x = 21

Therefore
Required number = x = 21

I HOPE this will USEFUL to u.

Let the TOTAL MARKS =120
no. of marks lost=11
the total score GOT by the STUDENT =120-11=109

9999999 is the numbercomes before

Let ONE SIDE be x
then other TWO will be x+3 and x+3+3
buy perimeter of triangle=81
x+x+3+x+6=81
3x=81-9
3x=72
x=24

Hey Friend ☺

p ( x ) = ( a + 1 )x^2 + ( 2a + 3 )x + ( 3a + 4 )

The SUM of zeroes is - 1

i. e.

2a + 3 = - 1

》2a = - 1 - 3

》2a = - 4

》a = - 2

Product of zeroes = ( 3a + 4 )

= 3 ( - 2 ) + 4

= - 6 + 4

= - 2

So the product of zeroes is - 2

HOPE it helps you ..!

Definition of MEAN proportional, geometric mean like the square root (such as X) of the PRODUCT of two numbers (such as a and B) when expressed as the MEANING of a proportion (such as a/x = x/b)

THANK you for your question.

Let the uniform/original speed be x km/hr.

Then according to question,

360/x = 360/x+5 + 48/60 

We divide 48 by 60 in order to convert it into hr from min.

360/x - 360/x+5 = 48/60

360(x+5) - 360(x) / x(x-5) = 4/5

5(360 x - 360 x + 1800) = 4 (x² - 5 x)

5(1800) = 4(x² - 5 x)

9000 = 4 x² - 20 x

⇒ 4 x² - 20 x - 9000

(÷4)

⇒ x² - 5 x - 2250

⇒ x² - 50 x + 45 x - 2250

⇒ x(x-50) + 45(x-50)

⇒ (x+45)(x-50)

Then x = -45 km/hr, 50 km/hr

As speed cannot be negative.

Hence original/uniform speed is 50 km/hr.

Given :Total number of cadets = 202500
Number of cadets to arrange in PERFECT square rows = 202500
number of rows = number of cadets in each row,
Total number of cadets = number of rows × number of cadets in each row
202500 = number of rows × number of cadets in each row
202500 = (Number of cadets in each row)²
Number of cadets in each row = √202500
Number of rows = √ (2×2)×(5×5)× (5×5)×(3×3) ×(3×3)
Number of cadets in each row = 2 × 5 ×5 × 3× 3 = 450

Hence the number of cadets in each row is 450 .

I am considering that your question is like this:-

The denominator of a fraction exceeds the numerator by 2. If 5 be added to the numerator the fraction increase by UNITY. The fraction is? 
Here is the answer :-

Numerator = x


then,

Denominator = x + 2

(x+5)/(x+2) = x/ (x+2) +1

(x+5)/(x+2) - x/(x+2) =1

(x+5 -x)/(x+2)= 1

5/(x+2) = 1

5 = x + 2

x = 3

so,

numerator = x = 3
denominator = x+2 = 3+2 = 5

Fraction = 3/5

2/9 th of BOOK is 40 pages 1/9 would be 20 1 would be 180 2/9:40::1:180

Angle sum property of triangle

A + B +C = 180°

Let the angle here be 5x ,3x and 7x

Then ,
5x + 3x + 7x = 180°
15x = 180°
x = 12°

A = 5x = 5×12=65°
B = 3x = 3×12° = 36°
C = 7x = 7× 12 = 84°

Since all the angles are LESS than 90° , they are acute angles.

Hence PROVED

HEY.......
HERE IS U R ANSWER
===================================

LET THE PRICE BE 100
AFTER INCREASE IT WILL BE 120
AS 20% OF 100 IS 20.

THE PRICE SHOULD BE DROPPED BY 20
SO THAT IT WILL BE 100
SO %AGE = 20/120 * 100
= 1/6 * 100
= 100/ 6 = 16.67%

5 is only SINGLE
so, we MULTIPLY by 25
then, it is a perfect cube.

Answer:-

Thinking Process:-

Here, we have to take any two consicutive or positive integer.

After that squaring and adding both the number and CHECK it is a even but not divisible by 4.

Solution:-

Let x = 2m + 1

Let y = 2m + 3

Here, both are positive integer, for  every positive integer m.

⇒ x² + y² = (2m  +1)² + (2m + 3)²

⇒ x² + y² = 4m² + 1 + 4m + 4m² + 9 + 12m      [∵ (a + B)² = a² + 2AB + b²]    

⇒ x² + y² = 8m² + 16m² + 10 = even

⇒ x² + y² = 2(4m² + 8m + 5) or (2m² + 4m + 2)

Hence, x² + y² is even for every positive integer m but not divisible by 4.

To prove this FIRST we have to prove that ROOT 3 is IRRATIONAL number .
From above we PROVED that root 3 is irrational
so 1/2+root 3 is also irrational

The HCF of 210 and 55 is 5
so,
            5 = 210*5 + 55Y
     -1045 = 55y
             y = -1045 / 55
             y = -19
