Write an equation for the nth term of the arithmetic sequence. Then find a 30
AnnZ [28]

Answer:

The nth term is given by: a_n = -9 + 3(n-1)

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

a_n = a_1 + (n-1)d

In which a_1 is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that a_1 = -9, r = -6 - (-9) = -6 + 9 = 3. So

a_n = -9 + 3(n-1)

30th term:

a_30 = -9 + 3(30-1) = -9 + 87 = 78

The 30th term is 78.

!!PLEASE HELP ME!!<br> im stuck ):
yuradex [85]

Answer:

x = 5

Step-by-step explanation:

Since these are similar triangles all you need to do is figure out how much "x" has gotten smaller.

First take the line DE length (16) and divide it by line BC (8)

16 / 8 = 2

Now divide line BD by 2

10 / 2 = 5

x = 5

How many questions would I have to miss on a 25 question test to get 88% ?
N76 [4]
Let's start with the question, how many questions do you need to get 88%?

so were are looking for
?/25 = 88% and 88% is also 0.88 so we can multiply 25 by 0.88

we get 22


But this doesn't here. the question asks us how many mistakes do you need. you can just subtract 22 from 25

25-22= 3
you need 3 misses to get 88%
