One lap around a track is 1/4 mile long if you ran around the track three times and then ran 5/6 mile home how far did you run

19/12 or 1 7/12

Step-by-step explanation:

1/4*3=3/4

3/4+5/6

9/12+10/12= 19/12

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
