Question

If a = 5.0 + 0.1 and b = 5.0 + 0.2 then 2b - a is
equal to​

Answer 1

Answer:

5.3

Explanation:

a = 5+0.1 = 5.1

b = 5+0.2 = 5.2

2b = 2×5.2 = 10.4

2b-a = 10.4 - 5.1 = 5.3

Answer 2

Answer:

If a = 5.0 + 0.1 and b = 5.0 + 0.2 then 2b - a is

equal to 11

Explanation:

Here a = 5.0 + 0.1 and b = 5.0 + 0.2

We have to found value of 2b-a

We are substituting value of a and b in 2b-a and get,

2(5.0.+0.2)-(0.5+0.1) = 2x5.2-0.6= 10.4-0.6= 11

Therefore value of 2b-a is 11 if a = 5.0 + 0.1 and b = 5.0 + 0.2

This is a simple value putting math.
