X=40.
-6x+10x=160
4x=160 divide by 4 on both sides
And your answer is 40
The answer is H, or x = 0.6.
Answer:
Second choice.
Step-by-step explanation:
Option 1: solve the inequality. Add 7 to both sides, and multiply by -3 (don't forget that this makes the inequality switch direction!) to get
or x > -9
Option 2. Plug 0 in it. You get -7 < 20, which is obviously true. So 0 is in the set of solution and it means B and C are possible solutions. So let's check another easy value. let's say -10. replacing it you get
or
. But 23 is obviously greater than 20, which means -10 is not a part of the solution. Correct answer is B
