Answer:

#5/2=2 1/2=2.5#

Explanation:

To evaluate this expression substitute x = 10 into it.

#rArr(2x+5)/x=((2xx10)+5)/10=(20+5)/10=25/10#

There is a common factor of 5 which simplifies to.

#25/10=cancel(25)^5/cancel(10)^2=5/2#

#5/2" may be expressed as a mixed number or as a decimal"#

#rArr5/2=2 1/2=2.5#

Any of these 3 is the value of the expression.
