Explanation:
The given expression is :
[tex]\dfrac{w}{2}-12=18[/tex]
The value of w can be solved as follows :
Add 12 to both sides,
[tex]\dfrac{w}{2}-12+12=18+12\\\\\dfrac{w}{2}=30[/tex]
Cross multiplying, we get :
[tex]w=2\times 30\\\\w=60[/tex]
Leon should have made mistake at last step where instead of multiplying 2 and 30 he divides 30 by 2 so that he get 15 as answer.
Answer:
Leon's mistake was Step 2

Answer:
METAMORPHIC
Explanation:
Generally, rocks can be classified into three types in nature. they are: igneous, sedimentary and metamorphic rocks. Each of these rocks has individual mode of formation.
Metamorphic rock is one formed due to the application of heat and pressure on an originally existing rock. Metamorphic rocks are crystalline because of their nature, and contain some minerals.
Thus, arranging the word appropriately gives METAMORPHIC.
Rearranging EMAIHTPCMER would give us the word METAMORPHIC
Metamorphic Rock is one of the types of rock that is formed as a result of subjection to extreme heat and pressure. They are usually a byproduct of igneous and sedimentary rocks.
There are three major types of metamorphic rock and they are:
Contact: This occurs when molten lava directly changes an already existing rockRegional: This happens in a large area, where rocks are broken during mountain buildingDynamic: This is caused by large amounts of heat and pressure on the rocks which make them change shape.Some examples of metamorphic rocks include:

What is a temperature inversion in the atmosphere?
The Stratosphere and the Thermosphere have temperature inversions in them.
Describe what causes the temperature inversions in each of these two layers the atmosphere?
I'm so clueless of this I need some help
Answer:
1 A temperature inversion is a deviation from the normal decrease of atmospheric temperature with altitude in the lower portion ( troposphere) of a planetary atmosphere ( atmosphere, Structure). Temperature inversions inhibit vertical motion, because the warmer air is at a higher altitude and tends to remain there.
question 2
An inversion exists when temperature increases with altitude. The figure below shows the four layers: the Troposphere, the Stratosphere, the Mesosphere, and the Thermosphere. Between each layer exists a "pause" in which the temperature remains constant with height.
Which group of people have the ability to access GPS systems locally, nationally and world wide?
Only the capitalists and elite of the world
Anyone with access to wireless internet or advanced radio technology
Anyone with over $500 in technology software
Rural villages and those in high places
Answer:
Anyone with access to wireless internet or advanced radio technology
Explanation:
Anyone with access to wireless internet or advanced radio technology have the ability to access GPS systems locally, nationally and world wide.
GPS is the short form of Global Positioning Systems. It is made up of a system of satellites which are used to locate positions on earth. They work on principle of triangulation.
Most of these system of satellites are accessible over a wireless internet. For example, most of our mobile phone have this ability. Also, over advanced radio technology we can access these gps systems. This is used mostly in the military for more secured access.What are tectonic plates?

Explanation:
Which statement best describes wavelengths of sunlight that are longer than 700 nanometers? These wavelengths form the infrared part of the spectrum. These wavelengths form the ultraviolet light of the spectrum. These wavelengths are shorter than the wavelengths of visible light. These wavelengths are part of the visible light spectrum.
Answer:
Option A is the appropriate approach.
Explanation:
Throughout reality, the sun produces light across all colors, but rather because yellow would be the strongest wavelength of the sun, that's color that only the image recognizes through our naked eyes, although you can never glance up towards the sky. The infrared portion including its spectrum is created by some of these wavelengths.The other options offered are not relevant to the situation described. So, the solution here is just the right choice.
Answer:
Answer: These wavelengths are longer than wavelength of visible light. These wavelengths form the infra-red part of the spectrum.Explanation:
These wavelengths form the infra-red part of the spectrum.
Explanation:
Solar spectrum has lies in three parts of the electromagnetic spectrum - Ultraviolet, visible and infra-red.
Visible light lies from 400 nm to 700 nm.
Ultraviolet region precedes visible spectrum and has shorter wavelength than it.
Beyond visible spectrum, infrared part of the spectrum starts and has longer wavelength than it.
Physical features and environmental conditions primarily influence a region's _____.
a.form of government
b.social class system
c.population distribution
d.religious beliefs
Answer:
c. population distribution
Explanation:
The physical and environmental conditions of a region greatly influence the population distribution of a country. This is because it is these conditions that determine whether many needs of the population will be met.
When the physical and environmental conditions are able to supply the population's needs, it is common for this region to have a larger population distribution, on the other hand, when the physical and environmental conditions are not able to supply these needs, the population distribution is smaller.
