Answer:
Inequality which are true for x = 20:
Option A, C and D are true
Step-by-step explanation:
Given: Value of x =20
Option A:
\(x+30<3x\)
Substitute the value of x =20
\(20 + 30 < 3(20)\)
50 < 60 True.
Option B:
\(x-5<2x-35\)
Substitute the value of x =20
\(20 - 5< 2(20) - 35\)
15 < 5 False.
Option C:
\(\frac{x}{4}
Substitute the value of x =20
\(\frac{20}{4} < 20-12\)
5< 8 True.
Option D:
\(2x
Substitute the value of x =20
\(2(20) < 20+22\)
40 < 42 True.
