finding which number supports the idea that the rational numbers are dense in the real numbers?

a. a fraction between ĉ and 3
b. an integer between -11 and -10
c. a whole number between 1 and 2
d. a terminating decimal between -3.14 and -3.15
o

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

1) is right
