Answer : ) 1. which number is not the sum of three consecutive integers? a. 65 b. 150 c. 42 d. 572. train a leaves a station traveling at 48 kilometers per hour. four hours later, train b leaves the same station traveling in the same direction at 68 kilometers per hour. what equation can you use to find the time t in hours that it took train b to catch up with train a, and what is the value of t? a. 68(t – 4) = 48t; t = 13.6 hoursb. 48(t + 4) = 68t; t = 10.6 hoursc. 68(t + 4) = 48t; t = –9.6 hoursd. 48(t + 4) = 68t; t = 9.6 hours3. the sum of two consecutive integers is –27. if n represents one of the integers, what equation can you write to find the value of the two integers and what are the integers? a. n + (n – 1) = –27; –14 and –15b. n + (n + 1) = –27; –14 and –12c. n + (n + 1) = –27; –14 and –13d. n + (n + 1) = –27; –14 and –154. the length of a rectangle is one fourth its width. the perimeter of the rectangle is 60 centimeters. if w represents the width of this rectangle, which expression represents its length? a. l = 1 over 4wb. l = 4wc. l = 60 – wd. l = 60 – 2w
