Infinite Algebra 2
Irina-Kira [14]
The first problem, all you need to do is combine like terms then isolate the n:
4n-2n=4
~subtract 2n from 4n (2n)
2n=4
~then divide both sides of the equation by 2 to isolate the n
n=4

The second problem follows the same steps of combining like terms and isolating the variable. Here, you'll have to combine 2 like terms:
-12=2+5v+2v
~first combine the variables which is just 5v+2v which is 7v
-12=2+7v
~then subtract 2 from both sides to isolate the 7v
-14=7v
~then divide both sides by 7 to isolate the v and get your answer
-2=v

Hope that helped!

katen-ka-za [31]

Answer:

  33, 39, 45, 51

Step-by-step explanation:

The general term of an arithmetic sequence is given by the formula ...

  an = a1 + d(n-1) . . . where a1 is the first term and d is the common difference

Comparing this formula to the one you are given, you see that ...

  a1 = 33, d = 6

This means the first term is 33, and each successive term is 6 more than the previous one. The first 4 terms are ...

  33, 39, 45, 51
