How can you visit the sun without burning up worksheet answer key
Lesechka [4]

How can you visit the sun without burning up worksheet answer key is a heading for a worksheet that involves mathematical questions to calculate. The attached file displays those mathematical questions.

Before that, the sun is known as a star that is located in the middle of the Solar system. It is a virtually flawless sphere of hot plasma that has been heated by nuclear fusion processes in its center, thereby radiating energy as infrared radiation and ultraviolet light.

It is nearly impossible to visit the sun due to the degree of its temperature and radiation.

  • From the image attached below which depicts the heading to the question, we have:

a) 5(x - 9) = 2x + 15

Open brackets

5x - 45 = 2x + 15

Collect like terms

5x - 2x = 45 + 15

3x = 60

x = 60/3

x = 20

b) \mathbf{ 7n - 20 = 9(4n + 1)}

Open brackets

7n - 20 = 36n + 9

7n - 36n = 20 + 9

- 29 n = 29

n = - 29/29

n = - 1

Therefore, from the given information, we can conclude that It is nearly impossible to visit the sun due to the degree of its temperature and radiation. Also, the value of x = 20 and the value of n = -1
