I am only guessing that you mean:
(n-2)/-3<7 if so, multiply both sides by -3 (and reverse the direction of the inequality sign because of negative mulitplication!)
n-2>-21 add 2 to both sides
n>-19
Answer: 17.7
Step-by-step explanation:
69/ 3.9%•100= 17.69= 17.7
Answer:
False
Step-by-step explanation:
a>b
Let c> 0 then ac>bc because we are multiplying by a positive number
if c<0 then ac < bc because we are multiplying by a negative number we have to flip the inequality symbol
Since we do not know the value of c, we have to go with false
Answer:The 20th term of the arithmetic sequence is 55
Step-by-step explanation:
A sequence can be described using the rule:
an = –2 + 3(n-1)
Where
an is the value of the nth term of the arithmetic sequence.
- 2 is the first term of term of the sequence.
n is the number of terms in the sequence.
To determine the 20th term, we will substitute n = 20 into the equation. It becomes
a20 = - 2 + 3(20 - 1)
a20 = - 2 + 3×19
a20 = -2 + 57 = 55
