1. You multiply both sides by a
2. You're done!!!
I think diagram of number D show the inverse of R[X]
Answer:
0.6-2.1=1.5
Step-by-step explanation:
0.6-2.1=-1.5
0.6-2.1= - I2.1-0.6I
2.1
-0.6
--------
1.5
1/2+-2/5t(+2/5)=1/5t+t(+2/5)
simplify
1/2=2 and 3/5t
change to a decimal
.5 = 2.6t
divide both sides by 2.6
.5/2.6 2.6t/2.6
you get T= .3125
