Answer:


(31x)/(30)

Explanation:

Before adding we require the fractions to have a common denominator

The lowest common denominator of 2, 5 and 3 is 30, thus


(15x)/(15(2)) +
(6x)/(6(5)) +
(10x)/(10(3))

=
(15x)/(30) +
(6x)/(30) +
(10x)/(30)

Add the numerators leaving the denominator

=
(15x+6x+10x)/(30) =
(31x)/(30)

Answer:
\bold{c)\quad (31x)/(30)}

Explanation:


(x)/(2)+(x)/(5)+(x)/(3)\\\\\text{The LCD of 2, 5, and 3 is }2\cdot 5\cdot 3=30\\\text{Multiply each term so their denominator is 30:}\\\\\\(x)/(2)\bigg((15)/(15)\bigg)+(x)/(5)\bigg((6)/(6)\bigg)+(x)/(3)\bigg((10)/(10)\bigg)\\\\\\=(15x)/(30)+(6x)/(30)+(10x)/(30)\\\\\\=(15x+6x+10x)/(30)\\\\\\=\large\boxed{(31x)/(30)}
