Question

if x=7/8 and y= -5/4 than find (1) (x+y) (2) x-y​

Answer 1

Answer:

1) -3/8     2)17/8

Step-by-step explanation:

1) x = 7/8 ,  y = -5/4

x+y = 7/8 +(-5/4)

      = 7/8 - 10/8

      = -3/8

      = -0.375

2) x - y = 7/8 -(-5/4)

           = 7/8 + 10/8

           = 17/8

           = 2.125

$\blue{\mathbb{Here\:is\:your\:answer}}$

$\rule{400}{2}$

$\boxed{\green{\texttt{Given}}}$

$\orange{x=\frac{7}{8}}$

$\orange{y=\frac{-5}{4}}$

$\blue{(x+y)}$

$1) \frac{7}{8} + ( - \frac{5}{4} )$

$= \frac{7 - 10}{8}$

$= - \frac{3}{8}$

$\rule{400}{2}$

$\blue{x-y}$

$2) \frac{7}{8} - ( - \frac{5}{4} )$

$= \frac{7}{8} + \frac{5}{4}$

$= \frac{7 + 10}{8}$

$= \frac{17}{8}$
