Answer:

x+ (x+1) = 55

27, 28

Step-by-step explanation:

Let x = first number

x+1 is the next consecutive number

x+ (x+1) = 55

Combine like terms

2x+1 = 55

Subtract 1 from each side

2x+1-1 = 55-1

2x = 54

Divide by 2

2x/2 = 54/2

x = 27

The numbers are 27 and 28

An Ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. These biotic and abiotic components are linked together through nutrient cycles and energy flows. Energy enters the system through photosynthesis and is incorporated into plant tissue. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter, decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes.

Step-by-step explanation:

Dod you mean

=  \frac{ {n}^{5} }{ {n}^{ - 2} }  \times  \frac{ {n}^{2 - 6} }{ {n}^{8} }

=  {n}^{5 - ( - 2)}  \times  {n}^{2 - 6 - 8}

=  {n}^{7}  \times  {n}^{ - 12}

=  {n}^{7 + ( - 12)}

=  {n}^{ - 5}  =  \frac{1}{ {n}^{5} }

So here's the question
Lesechka [4]
Yes, is subtraction, to get their "difference".

first off, let's convert the mixed fractions, to "improper", and then subtract.

\bf \stackrel{red~yarn}{9\frac{1}{5}}-\stackrel{blue~yarn}{3\frac{11}{25}}

\bf -------------------------------\\\\&#10;\stackrel{mixed}{9\frac{1}{5}}\implies \cfrac{9\cdot 5+1}{5}\implies \stackrel{improper}{\cfrac{46}{5}}&#10;\\\\\\&#10;\stackrel{mixed}{3\frac{11}{25}}\implies \cfrac{3\cdot 25+11}{25}\implies \stackrel{improper}{\cfrac{86}{25}}\\\\&#10;-------------------------------\\\\&#10;\cfrac{46}{5}-\cfrac{86}{25}\impliedby \textit{our LCD is 25}\implies \cfrac{(5\cdot 46)~~-~~(1\cdot 86)}{25}&#10;\\\\\\&#10;\cfrac{230~-~86}{25}\implies \cfrac{144}{25}\implies 5\frac{19}{25}
