Changes made to your input should not affect the solution:

(1): "2.4" was replaced by "(24/10)".

STEP

1

:

           12

Simplify   ——

           5  

Equation at the end of step

1

:

                     12          

 (2n - 9) -  ((0 -  (—— • n)) +  4)

                     5            

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  5  as the denominator :

        4     4 • 5

   4 =  —  =  —————

        1       5  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-12n + 4 • 5     20 - 12n

————————————  =  ————————

     5              5    

Equation at the end of step

2

:

             (20 - 12n)

 (2n - 9) -  ——————————

                 5      

STEP

3

:

Rewriting the whole as an Equivalent Fraction :

3.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

              2n - 9     (2n - 9) • 5

    2n - 9 =  ——————  =  ————————————

                1             5      

STEP

4

:

Pulling out like terms :

4.1     Pull out like factors :

  20 - 12n  =   -4 • (3n - 5)  

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

(2n-9) • 5 - (-4 • (3n-5))     22n - 65

——————————————————————————  =  ————————

            5                     5    

Final result :

 22n - 65

 ————————

    5

what is the process called when a glacier deposits rocks in oceans and lakes?

Answers

The process in which a glacier deposits rocks in oceans and lakes is called deposition

A deposition is the process called when a glacier deposits rocks in oceans and lakes. Sediment that has been carried by the wind, water, sea, or ice is deposited. Sand, mud, and pebbles can all be used to transport sediment, as can salt dissolved in water. In the future, evaporation or organic activity may deposit salts.

What is the sediment deposited by glaciers called?

The sediment left behind by a glacier is known as a glacial till. It covers glacier forefields and is common throughout glacial environments. It can also be mounded to create moraines and other glacier landforms.

Sediments left behind by a moving glacier settle during glacial deposition. Rocks and sediment are carried off the land by glaciers as they pass. Glacial till refers to the glacier's collection of unsorted sediment deposits. Moraines are the piles of till that have been left behind by the edges of previous glaciers.

Questions on tectonic plates, could someone help?

What types of geological events or changes occur at divergent plate boundaries?

What types of geological events or changes occur at convergent plate boundaries?

What types of geological events or changes occur at transform plate boundaries?

Explain how these geological processes and interactions have changed Earth's surface through the years. Be sure to use evidence to support your answer.

Answers

Answer:

1) A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.

2) A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction) This can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

3) In a transform plate boundary, two plates slide past each other, conserving the plates. Shallow-focus earthquakes are generated here. The earth has experienced various geological processes, such as weathering and erosion of rocks, earthquakes, volcanic eruptions, mass extinction events, plate tectonic movements.

4) these geological processes and interactions have changed Earth's surface through the years by causing more geological processes such as "earthquakes, volcanic eruptions, and mass extinction events" these changes have also "created a new oceanic crust" stated by the NOAA
