Just plot it and solve by counting
3 - 2x + 5 < -4(x + 2)
-2x + 8 < -4(x + 2)
-2x + 8 < -4x - 8
-2x + 8 + 4x < -8
2x + 8 < -8
2x < -8 - 8
2x < -16
x < -16/2
x < -8
Answer: A) x < -8
3/5n - 4/5 = 1/5n....multiply everything by 5 to get rid of the fractions
3n - 4 = n
-4 = n - 3n
-4 = -2n
-4/-2 = n
2 = n <==
Answer:
Subtract 2.5 after every term.
Step-by-step explanation:
13-2.5=10.5
10.5-2.5=8
So on and so forth. Therefore, the rule is subtracting 2.5 after every term.
