The digit at ones place of a 2-digit number is four times the digit at tens place. Thethe given number.ined bynumber obtained by reversing the digits exceeds the given number by 54. Find​

Answer»

Given :-

  • The digit at ones place of a 2-digit number is four times the digit at TENS place. The the given number obtained by REVERSING the digits exceeds the given number by 54.

To FIND :-

  • Required numbers

Solution :-

Let the tens digit be x then ones digit be y

  • Original number = 10x + y

The digit at ones place of a 2-digit number is four times the digit at tens place.

→ y = 4x ---(i)

The the given number obtained by reversing the digits exceeds the given number by 54.

  • Reversed number = 10y + x

→ 10x + y + 54 = 10y + x

→ 10x - x + y - 10y = - 54

→ 9x - 9y = - 54

→ 9(x - y) = - 54

→ x - y = - 6 --(ii)

Put the value of y in equation (ii)

→ x - 4x = - 6

→ - 3x = - 6

→ x = 2

Substitute the value of x in equation (i)

→ y = 4x

→ y = 4 × 2

→ y = 8

Hence,

  • Tens digit = x = 2
  • Ones digit = y = 8

Therefore,

  • Original number = 10x + y = 28
  • Reversed number = 10y + x = 82

Solve the eqn of x +5= 12 by using trial and error method in the table​

Answer»

Answer:

let we choose X = 1

so 1+ 5 = 6

which is not a solution

let we choose x = 2

so 2 + 5 = 7

which is not a solution

let we choose x = 3

so 3 + 5 = 8

which is not a solution

let we choose x = 4

so 4 + 5 = 9

which is not a solution

let we choose x = 5

so 5 + 5 = 10

which is not a solution

let we choose x = 6

so 6 + 5 = 11

which is not a solution

let we choose x = 7

so 7 + 5 = 12

which is a solution

So x = 7

I have a total of 300 in coins of denomination Rs1 , Rs 2,Rs5 . The number of Rs 2coins is 3 times the number of Rs 5 coins . The total number of coins is 160 . how many coins of each demination are with me ?​

Answer»

Answer:

Let the NUMBER of coin 5 = Rs.x

so the number of coin 2 = 3x

so the number of coin 1 = 160 - 4X

so amount of rs.5 = 5x

so the amount of rs.2 = 6x

a/q

5x + 6x + 160 - 4x = 300

7x = 300 - 160

7x = 140

x = 20

so the number of coin of 5 = 20 coins

so the number of coin of 2 = 60 coins

so the number of coin of 1 = 80 coins

Step-by-step EXPLANATION:

angle A=k/3

angle B=K/6

angle C=K/8

K/3+K/6+K/8=180°

K=288

therefore SUBSTITUTE k value we GET

How I will divide 10 5/6 by 3 1/4

Answer»

Answer:

I. Division of a fraction by a WHOLE number:

For example:

(i) Divide 3/5 by 12

Solution:

3/5 ÷ 12

= 3/5 ÷ 12/1

= 3/5 × 1/12

= (3 × 1)/(5 × 12)

= 3/60

= 1/20

Step I: Find the reciprocal of the whole number and multiply with the fractional number as usual.

Step II: EXPRESS the PRODUCT in its lowest terms.

(ii)  Solve: 5/7 ÷ 10

= 5/7 ÷ 10/1

= 5/7 × 1/10

= (5 × 1)/(7 × 10)

= 5/70

Step I: Find the reciprocal of the whole number and multiply with the fractional number as usual.

Step II: Express the product in its lowest terms.

II. Division of a fractional number by a fractional number:

For example:

(i) Divide 7/8 by 1/5

Solution:

7/8 ÷ 1/5

= 7/8 × 5/1

= (7 × 5)/(8 × 1)

= 35/8

= 4 3/8

Step I: Find reciprocal of 1/5.

Step II: Multiply 7/8 by it.

Step III: Express the product in its simplest FORM.

(ii) Divide: 5/9 ÷ 10/18

Solution:

5/9 ÷ 10/18

= 5/9 × 18/10

= (5 × 18)/(9 × 10)

= 90/90

= 1

Step I: Find reciprocal of 1/5.

Step II: Multiply 7/8 by it.

Step III: Express the product in its simplest form.

III. Division of a mixed number by another mixed number:

For example:

(i) Divide 2 ¾ by 1 2/3

Solution:

2 ¾ ÷ 1 2/3

= 11/4 ÷ 5/3

= 11/4 × 3/5

= (11 × 3)/(4 × 5)

= 33/20

= 1 13/20

Express the mixed numbers as improper fractions and multiply as usual.

(ii) Divide: 2  4/17 ÷ 1  4/17

Solution:

2  4/17 ÷ 1  4/17

= 38/17 ÷ 21/17

= 38/17 × 17/21

= (38 × 17)/(17 × 21)

= 646/357

= 38/21

= 1 17/21

Step-by-step explanation:

42.

I don't understand this answer. Pls help​

Answer»

Step-by-step explanation:

complementary ANGLES are those , whose sum is <=90°

in the question it is given that (a+15)° and 2a° are complementary

therefore

(a+15)° + 2a° =90 °

a+2a+15=90°

3a° =90-15

3a°=75

= 25

Now,

SINCE a=25 so (a+15) = 25+15 = 30°

2a = 2x 25 = 50°
