The value of an investment is expected to grow 5% per year. How long will it take for the value to double?

A). About 4 years
B). About 7 years
C). About 14 years
D). About 23 years

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

for b its (t) and c its (d)
