if a=-11/27,b=4/9 and c=-5/18,then verify that a+ (b + c) = (a + b) + C.
Answers
Answer:
Step-by-step explanation:
First figure out what a,b and c is then substitute. A=-0.407(407 is recurring) B=0.4(4 is reccuring) and C=-0.27(the 7 is reccuring) so the equation will be -0.407+(0.4+-0.27)=(-0.407+0.4)+-0.27 both sides equal -0.277. you can verify this by knowing that you are just adding in this equation do it does not matter if you rearrange the numbers or add two numbers together before another one. So weather you add c+a+b the answer will still be the same as adding a+b+c.
Step-by-step explanation:
L. H. S=a+(b+c)
=11/27+(4/9+5/18)
=11/27 + 8+5/18
=11/27 + 13/18
=22+39/54
=61/54
=1whole7/54
R. H. S=(a+b)+c
=(11/27+4/9)+5/18
=23/27+5/18
=46/54+15/54
=61/54
=1 whole 7/54
Therefore, L. H. S=R.H.S,hence verified
