Flora volunteered to drive 210 miles to pick up her sister from summer camp. she stopped 140 miles into the trip to eat lunch. write a fraction in simplest form of the trip she had completed by lunch, then write the fraction as a decimal. also, write a fraction and decimal that represents the part of the entire round trip that has been completed.

1.2/3

2.0.66

3.210/210

4.1

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
