Question

The value of b is twice the value of a. Find their values. ​

Answer 1

B = 24 and A = 12

Total = 100

So 64 + a + b = 100

A + b = 36

A + 2A = 36

A = 36/3 = 12

B = 2 into 12 = 24

Answer 2

Answer:

a=12 , b=24

Step-by-step explanation:

9+a+40+b+15=100

64+a+b=100 [ --- 1 ]

given that:

b=2a [----2 ]

therefore,putting the value of b in eqn. 1

64+a+2a=100

64+3a=100

3a=100-64

3a=36

a=36/3

a=12

putting the value of a in eqn. 2

b=2a

b=2×12

b=24
