Question

x is equal to 2 by 5 Y is equal to minus 4 by 3 Z is equal to 8 by 9 then verify that X + Y + Z is equal to X + Y + Z​

Answer 1

Answer:

X+Y+Z=(2/5)+(-4/3)+(8/9)

          =0.4-0.93+0.89

          =0.36

Step-by-step explanation:

Answer 2

• x = 2/5

• y = -4/3

• z = 8/9

___________ [ GIVEN ]

• We have to verify that x + y + z = x + y + z

___________________________

=> x + y + z = $\dfrac{2}{5}$ + $\dfrac{(-4)}{3}$ + $\dfrac{8}{9}$

=> $\dfrac{2}{5}$ - $\dfrac{4}{3}$ + $\dfrac{8}{9}$

LCM of 3, 5 and 9 is 45

=> $\dfrac{2(9)\:-\:4(15)\:+\:8(5)}{45}$

=> $\dfrac{18\:-\:60\:+\:40}{45}$

=> $\dfrac{-2}{45}$
