The answer is B.
This is because the triangle is an isosceles triangle, meaning that the answer to 4x-8 = x+4
You can rearrange this question to put the x’s on both sides and the integers on both sides so that 4x-x = 4 + 8. This cancels down to 3x = 12. To find x, divide 12 by 3, which is 4.
To check this answer, you can input 4 into both of the equations. (4 x 4) - 8 = 8, and 4 + 4 is also 8. Hence, you know x = 4.
Another, more time-consuming way of doing this question would be to simply input each possible value (A, B, C and D) into both equations until the both equations came out with the same number.
Hope this helped :)
Answer:
<u>In glaciers, North and South poles and some lakes.</u>
Explanation:
- As more than 70% of freshwater can be found in continental glaciers around the world. The rest is in icecaps and 0.5 % store in lakes and rivers, and swamps.
- Rest if possible may be found in the groundwater aquifers, hidden in remote and cut off lace of the world.
- Antarctica and arctic alone consist of a huge share of freshwater in the world which is stored in ice forms. While 97% of oceanic water is saline not fit for drinking.
- Various techniques are available for desalination of water but most of it not suitable for long term use. As it may have bacteria and harmful effects on the body. Due to climate change release of methane gas and other harmful greenhouse gases are quickly melting and depleting the freshwater r
