Need help fast (Taking a test) X varies directly with Y. Find the direct variation equation if y=18, x=2

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

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

its 4 because 2 times 2 is 4, if you double the number two you get four
