Answer:
-8
Step-by-step explanation:
-8 x 3 = -24
-24 is 16 units less than -8
The answer is 40 square root of 6.
You have to find the cube root of 27.
A same number when multiplied 3 times by itself will give the cube.
3√27 = 3 x 3 x 3
So the answer is 3
Simplify, simplify, simplify for problems like this. Add 6x to both sides to get 10x - 8 = 12. Then add 8 to both sides, so 10x = 20. Now divide by 10, and you get x = 2
Answer:
Step-by-step explanation:
This is called "solving an inequality".
The inequality can flip:
< becomes >
> becomes <
≤ becomes ≥
≥ becomes ≤
This only happens when we multiply or divide both sides by a negative number, or when we swap everything from either sides.
The thing to remember if there are two of the inequalities, we have to do everything to both sides. The goal stays the same. Get the "X" by itself in the middle.
-17 < 5 - 2x <= 9
-5 -5 -5
------------------------
-22 < -2x <= 4
Now we have to divide the -2 on both sides. Remember! Dividing by a negative means we have to FLIP THE SIGNS!
-22 < -2x <= 4
/-2 /-2 /-2
----------------------
11 > x >= -2
And your final answer would be that.
It can also be written this way:
-2 <= x < 11
