The number of seats in the first 27 rows of an arena form an arithmetic sequence with the second and third rows having 14 and 18 seats respectively. How many seats are in
row 25

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

the answer is b.)
