Answer:
x ⥶ -3
Step-by-step explanation:
2x - 7 -3x ⥶ 10
-x + 7 ⥶ 10
-x ⥶10 - 7
-x ⥶ 3
One ton is 2000 lbs so it is 3 and a half
Permafrost occurs in areas where the temperature of the ground remains below the freezing mark for two years or more. About a quarter of the Northern Hemisphere's landscape fits this definition. Most of the world's permafrost is found in northern Russia, Canada, Alaska, Iceland, and Scandinavia.
6x^2 + x - 12
= (3x - 4) (2x + 3)

Answer:
30°, 60°
Step-by-step explanation:
Let x represent the measure of the smaller angle in degrees. Then the larger unknown angle is 2x, and the sum of the angles in the triangle is 180°:
x + 2x + 90° = 180° . . . the sum of the angles in the triangle
3x = 90° . . . . . . . . . . . . subtract 90°, collect terms
x = 30° . . . . . . . . . . . . . divide by 3; this is the smaller angle
2x = 60° . . . . . . . . . . . .this is the larger angle
The two angles that are not the right angle are 30° and 60°.
