Simplifying 4m + 9 + 5m + -12 = 42 Reorder the terms: 9 + -12 + 4m + 5m = 42 Combine like terms: 9 + -12 = -3 -3 + 4m + 5m = 42 Combine like terms: 4m + 5m = 9m -3 + 9m = 42 Solving -3 + 9m = 42 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 9m = 42 + 3 Combine like terms: -3 + 3 = 0 0 + 9m = 42 + 3 9m = 42 + 3 Combine like terms: 42 + 3 = 45 9m = 45 Divide each side by '9'. m = 5
Answer:
1.A fertile area in desert where water is found.
2.This circular geologic feature is thought to be caused by an uplifted dome-geologist would classify it as a domed anticline-that has been eroded to expose the originally flat rock layers.
Canada's overall population density does not provide a clear picture about Canada's population.
Explanation:
Canada is one of the biggest countries in the world, second biggest to be more precise, but its population is pretty small for its territory. The population of this country is only slightly more than 37 million people, and when compared to the two countries closest to its size, China and the United States, having over 1.3 billion and over 320 million people, the differences is clear to see. Canada's population density is only 3.92 people on square km, making it one of the most sparsely populated countries in the world.
Those figures though doesn't give a clear picture about Canada's population. The southeastern part, southern part close to the U.S. border, and the southwestern part, all have medium to high population density, and the majority of the Canadians live in those parts of the country. On the other hand, the smaller percentage of the population lives in all of the rest of the country, and there are areas which don't have a single person living in them, and the small inhabited places are often several hundred km away from each other.
Other countries that have large territories, but small populations (for their size) which are not evenly distributed are:
- Mongolia
- Kazakhstan
- Australia
- Saudi Arabia
- Russia
