Answer:

x=34

Step-by-step explanation:

*it's kind of hard to read the number in parenthesis though but i think it's 5

both angles have to add up to 180º because they are co-exterior angles on parallel lines.

2(x+5)+102=180\\2(x+5)=78\\2x+10=78\\2x=68\\x=34

elena55 [62]

Answer:

She made 792 dollars that week. I'm assuming it is just asking for the yearly commission she made. That would be 41,184 dollars a year.

Step-by-step explanation:

7200 x 0.11 = 792 Weekly

52 Weeks in a year

792 x 52 = 41184 Yearly (if that's what it's asking for)

Find the 97th term of the arithmetic sequence 17, 26, 35, ...
vagabundo [1.1K]

Answer:

881

Step-by-step explanation:

Arithmetic sequences can be written as:

a_n = a_1 + (n-1)d\\a_1 \: is \: 17\\a_n = 17 + (n-1)d\\

The second term is 26,

26 = 17 + (2-1)d\\9 = 1d\\d = 9\\a_n = 17 + (n-1)*9\\a_n = 17 + 9n - 9\\a_n = 8 + 9n

So, the 97^t^h term is

a_9_7 = 8 + 9(97)\\a_9_7 = 8 + 873\\a_9_7 = 881
