Answer:
6.8, 16.6, 26.4, 36.2
Step-by-step explanation:
Let's write the sequence, d is the common difference:
- 3, - 3 + d, - 3 + 2d, -3 + 3d, - 3 + 4d, 46
Therefore 46 = -3 + 5d
5d = 49
d = 49/5 = 9.8
So the first arithmetic mean is -3 + 9.8 = 6.8. and the second is -3 + 2(9.8) = 16.6...
They are:
6.8, 16.6, 26.4, 36.2.
Distribute
3x+6>0
Subtract 6 from both sides
3x>-6
Divide both sides by 3
x>-2
Final answer: x>-2
Here's how to solve this equation:
4 - <span>√2x-5 = 1
</span><span>√2x-5 = 4-1
</span><span>√2x-5 = 3 (now we have to square both sides to get rid of the root)
</span><span>√2x-5=3 / ^2
</span>(<span>√2x-5)^2 = 3^2
2x-5 = 9
2x = 9+5
2x = 14
x = 14/2
x = 7
The correct answer is 7. </span>
