Answer: 3 ≥ x
Step-by-step explanation:
inequity would be 9 ≥ 2.40 + 2.20x
9 - 2.40 = 6.6
6.6 / 2.20 = 3
So it would be 3 ≥ x
Answer:
15
Step-by-step explanation:
Answer: (a) a = 3, and d=
(b) 
Step-by-step explanation:
Since we have given that
Arithmetic sequence be

As we know that
a denotes the first term.
d denotes the common difference.
So, 
Hence, a = 3, and d=

Hence, (b)

Add up all together 7+5+8+4+6=30 then take away 5 equaling 25 over 30 in simplest would be 5/6
