Solve the question: 4/5 (b-1)-1/b=1

We know that (4/5b - 4/5 - 1) / b = 1

Which means that b = 4/5b - 4/5 - 1

So we put variable on one side and numbers on the other side

So 1/5b = - 9/5

So b = - 9

answear:

a

step-by-step explanation: a

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
