4. two numbers are in ratio 8:3.if the sum of the number is 143, find the number.

5. 8x +3=27+2x

6.find which of the following number is a perfect square

a) 576 b) 11025

Answer 2

Answer:

2. *(((-3) / 5)- ((8) / 9))

= 0.57777777777

3. Value of x is 2/7 . Therefore, 2/7 is that number should be added to - 1 so as to get -5/7.

4. Given two numbers are in the ratio 8:3

so let the number be 8x and 3x 

According to the question we can write as 8x+3x=143

Which implies 11x=143

Again by transpoing x=143/11

Therfore x=13

So the number are 8x=8(13)=104 and 3x=3(3)=39

5. Given 8x+3=27+2x

By transposing the above equation we can weite as

⇒8x−2x=27−3

⇒6x=24

Again by transposing

⇒x=24/6=4
