Arestaurant sold 6 hamburgers every day for a week. how many hamburgers were sold during the week

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

5/12, or 5: 12

step-by-step explanation:

8.3 and the 3 is repeating

hope this .
