3x + 8 = 9 + 4x :First, subtract the 8 over to the right
3x = 1 + 4x :Then, subtract the 4x over to the left
-x = 1 :Then, divide the whole equation by the -1 attached to the x
<em><u>x = -1</u></em>

Answer:
20 miles
Step-by-step explanation:
The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).
d² = 12² +16²
d² = 144 +256 = 400
d = √400 = 20
The two trains are 20 miles apart.

<em>Additional comment</em>
You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)
Answer:A flower garden occupies 57 portion of a park. If the park has an area of 14725sqm, find the area of the garden
Step-by-step explanation:
The answer that you have derived is incorrect. Here is the correct way to solve it:
