There are two fraction models divided into equal sized portions the fraction represented by model a is less than the fraction represented by model b model 8 is divided into 12 portions and has five sections shaded model b is divided into five portions what do you know about the number portions shaded in model b

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
