Answer:
100
Step-by-step explanation:
Answer:
an = 2/5 * (5) ^ (n-1)
Step-by-step explanation:
The common ratio is 5
(That is the number we multiply by)
The formula is
an = a1 (r) ^ (n-1)
an = 2/5 * (5) ^ (n-1)
Answer:
This is the value in numbers.
5(n-12)>40
Step-by-step explanation:
Let's solve your inequality step-by-step.
5(n−12)>40
Step 1: Simplify both sides of the inequality.
5n−60>40
Step 2: Add 60 to both sides.
5n−60+60>40+60
5n>100
Step 3: Divide both sides by 5.
5n

n>20
Answer:
n>20
Step-by-step explanation:
Since the sequence above is an arithmetic sequence
For an nth term in an arithmetic sequence
A(n) = a + ( n - 1)d
where a is the first term
n is the number of terms
d is the common difference
From the question
a = 1/3
d = 1/2 - 1/3 = 1/6 or 2/3 - 1/2 = 1/6
Substitute the values into the above formula
That's
<h3>
</h3>
So the nth term of the sequence is
<h3>
</h3>
For a50 since we are finding the 50th term
n = 50
So we have
<h3>
</h3>
We have the final answer as
<h3>
</h3>

Answer:
x = -5
Step-by-step explanation:
-2x+2(5x+18)=-4
The first thing you would have to do is distribute the positive 2 with 5x and 18 so that means you would multiply those two number inside the parenthesis.
-2x+ 10x+ 36=-4 2(5x)=10x 2(18)=36
Now you combined like terms on the other side of the -4. So since -2x and 10x are like terms because of the variables you would do -2x+10x=8x. So now your equation is 8x+36=-4. So now you want you x by itself so you would subtract 36 on both sides so positive 36 subtracted by 36 is 0 now you subtract 36 to -4 so that equals -40 because you did -4-36=-40. So now you have 8x=-40 so now you divide both sides by 8x so -40/8=-5
x=-5
