Give three reasons on how assumptions can limit your perception of the world in a detrimental way

The world can cause harm from things such as famine, drought, disease, hunger, war, and health. They can also cause such things such as loss of materials, loss of money, loss of clothes, loss of items and more.

Explanation:

This can cause harm to everyone in the world including the children.

Also; because they lose time fixing these problems.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4
