What is the mean age (nearest year) of all the people in the office?

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

yes. we do proportions in probabilities.

the final price would be 29.6925

step-by-step explanation:

39.59 minus 25% equals 29.6925
