Question 251787: Solve
0.3(11x+4) ≥ 2.1 - (x+8)
this is what I have but I dont even come close to the answer choices
3.3x + 1.2 ≥ -2.1x + (-16.8)
3.3x-3.3x+1.2≥ -2.1x -3.3x + (-16.8)
1.2 + (-16.8) ≥-5.4x
-15.6/-5.4 = -5.4x/-5.4
-2.8888888888888888

0.3%2811x%2B4%29%3E=2.1-%28x%2B8%29 Start with the given inequality.


3.3x%2B1.2%3E=2.1-x-8 Distribute.


10%283.3x%2B1.2%29%3E=10%282.1-1x-8%29 Multiply both sides by 10 to clear out the decimals.


33x%2B12%3E=21-10x-80 Distribute and multiply.


33x%2B12%3E=-10x-59 Combine like terms on the right side.


33x%3E=-10x-59-12 Subtract 12 from both sides.


33x%2B10x%3E=-59-12 Add 10x to both sides.


43x%3E=-59-12 Combine like terms on the left side.


43x%3E=-71 Combine like terms on the right side.


x%3E=%28-71%29%2F%2843%29 Divide both sides by 43 to isolate x.

Answer:

So the solution is x%3E=-71%2F43


Which approximates to x%3E=-1.651
