Answer:
1. $8.55
2. $4.29
3. $17.00
4. $10.47
5. $40.31
Step-by-step explanation:
The given equality hold true when x = 2.
Put x = 2 in inequality.
2(2) + 3 = 4+3 = 7 = R.H.S.
For x = 4 and 6, L.H.S(2x+3) is greater than 7.
Hence for x = 2, 4 and 6, the above inequality holds true.
Hope this helps!
