3-1/3n&lt; 6;n&gt;-9 What is n???
r-ruslan [8.4K]

Answer:

i don't understand your question, but i'll try to the best of my ability.

the answer to that is:

-8.33333333333

Step-by-step explanation:

let me break this down into a way you might understand.

1: 3-1=2

2: 2 divided by 3=0.66666666666.

3: i don't know if the "< 6;n>", was meant to be in the equation, so i just added the rest of it up.

if that's not right let me know. i'm pretty clueless sometimes, and this might just be a higher level of math that i don't know.

you're welcome though, (i suppose..) and have a great day.

PLZ HELP!<br><br> Complete this proof. <br> Given: a | | b <br> Prove: ΔMOP ~ ΔRON
SashulF [63]
As shown in the given figure
line a // line b ⇒ given
MR  and  NP  are transversals 
So, for ΔMOP and ΔRON , we can conclude the following
(1)  ∠1 = ∠2 ⇒⇒⇒ alternative angles are congruent
(2) ∠ MOP = ∠ RON ⇒⇒⇒ vertical angles are congruent
(3) ∠ 4 = ∠ 3 ⇒⇒⇒ alternative angles are congruent

So, from 1,2 and 3
∴  ΔMOP <span>~ </span>ΔRON  by  AAA-Rule
