Question

I got 4 equations and 4 unknowns - how to solve em ? C + d = 130 , a + b = 140 , a + d = 110 and b + c = 160 . Is this solvable?

Answer 1

Answer:

I w_{n-1}^{b}=\frac{z_{n}}{\alpha z_{n-1}^{a}},\quad n\in {\mathbb {N}}_{0}

and

w_{n}^{b}=\beta ^{b} w_{n-2}^{bc}z_{n-2}^{bd},\quad n\in {\mathbb {N}}_{0},

from which it follows that

\begin{aligned} z_{n+1}=\alpha ^{1-c}\beta ^{b} z_{n}^{a}z_{n-1}^{c}z_{n-2}^{bd-ac},\quad n\in {\mathbb {N}}.

Answer:

Abstract nouns are a type of noun that you can't see or touch. A noun is a person, place or thing. ... An abstract noun may include an aspect, concept, idea, experience, state of being, trait, quality, feeling, or other entity that can't be experienced with the five senses.The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial. The term is most often applied to the Earth or some parts of Earth.
