Answer 1

Answer:

1) x + 8 = 20

3) x= 9

4) Ravi -30

Arjun - 70

Step-by-step explanation:

1) Let number be x,

(x+8) / 2 = 10

x + 8 = 10*2

x + 8 = 20

2) The sum of 3 and twice of a number is 5.

3) x +6 = 15

x = 15-6

x = 9

4) Let no. of marbles Ravi and Arjun have 3x and 7x

A/Q,

3x +7x =100

10x = 100

x = 100÷10

x =10

So,

Ravi = 3*10 = 30

Arjun = 7*10 = 70
