Answer:
The fourth term of the sequence is 3
Step-by-step explanation:
For an nth term in an arithmetic sequence
A(n) = a + (n - 1)d
Where n is the number of terms
a is the first term
d is the common difference
From the question
a = 12
d = - 3
So the fourth term of the sequence is
A(4) = 12 + (4 - 1)-3
= 12 + (3)(-3)
= 12 - 9
The final answer is
3

Answer:
x=13
Step-by-step explanation:
Supplementary angles add to 180 degrees
x+167 = 180
Subtract 167 from each side
x+167-167= 180-167
x = 13
Given : A mountain path is 12.1 miles long.
a hiker walks along the path at a rate of 1.96 miles per hour
To Find: in approximate how many hours will the hiker walk the entre trail
Solution:
Distance = 12. 1 miles
Speed = 1.96 mile/hr
Distance = Speed * time
12.1 = 1.96 * t
=> t = 12.1/1.96
=> t = 6.17
=> t ≈ 6 hrs 10 mins

2(n+9)=6 divide both sides by 2
n+9=3 subtract 9 from both sides
n=-6
check
2(-6+9)=6
2(3)=6
6=6
