Simplify to 6x - 21 < 4x - 8. Add 21 to both sides and subtract 4x from both sides. You will get 2x < 13. Divide both sides by two and you get x < 6.5
Well, we know that the total amount is $420, so we can already set one side of the equation. =420. Also, it said that the $420 is (equal to) 7/6b (b for balance).
Now just put it together! 7/6b=420 is your answer.
Answer:
- 30.75 < x < - 29.25
Step-by-step explanation:
Inequalities of the type | x | < a , always have solutions of the form
- a < x < a
Given
| 0.2x + 6 | < 0.15, then
- 0.15 < 0.2x + 6 < 0.15 ( subtract 6 from all 3 intervals )
- 6.15 < 0.2x < - 5.85 ( divide all intervals by 0.2 )
- 30.75 < x < - 29.25
Answer:27.9
Step-by-step explanation:
First step, 45/100 = 0.45
Multiply 0.45 by 62 = 27.9
