If 2(3x+5)>4x−5<3x+2; then x can take which of the following values?
- A8
- B6
- C−8
- D−10
Solution & Step-by-step Explanation
The given expression consists of a system of two inequalities:
2(3x+5)>4x−5
4x−5<3x+2
Let's solve the first inequality:
2(3x+5)>4x−5
6x+10>4x−5
6x−4x>−5−10
2x>−15
x>−7.5
Let's solve the second inequality:
4x−5<3x+2
4x−3x<2+5
x<7
Combining both inequalities, we get the range for x:
−7.5Now let's check the given options to see which value falls inside this range:
A) 8 (Not in range)
B) 6 (In range, since −7.5<6<7)
C) −8 (Not in range)
D) −10 (Not in range)
Therefore, x can take the value 6.
