Answer:
The twentieth term is 50.
Step-by-step explanation:
The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:
a1 = 3*1 - 10
a1 = -7
Therefore to find the twentieth term we need to make n equal to 20. This is done below:
a20 = 3*20 - 10
a20 = 60 - 10
a20 = 50
The twentieth term is 50.
Answer:
x=1/6
Step-by-step explanation:
3x+4=9x+3
isolate x
1=6x
1/6=x
now, the one below that, which is equivalent to that? well, just look above it
Answer:
2.96
Explanation:
37/x=100/8
(37/x)*x=(100/8)*x - we multiply both sides of the equation by x
37=12.5*x - we divide both sides of the equation by (12.5) to get x
37/12.5=x
2.96=x
x=2.96
