Answer 2

Answer:

I)let the number be x

and five added to twice means 2x of it

then the result is 51

2x+5=51

ii)let the number be x.

one fifth of 8 means1/5×8is substracted from twice of x

the result is 3

x-(1/5×8)=3

iii)let first even number be x

then the other even consecutive be x+2

their sum is 102

x+ x+2=102

iv)1/2×(x+5)=6
