Security Company A charges $3,468.00 for equipment and installation and then $6.34 per day to monitor the system and respond
to alerts. Security Company B charges only $891.00 for the installation of their equipment, but $15.47 per day to monitor the
system and respond to trouble. Which system of equations can be used to determine the number of days it takes x for the two
companies to charge the same amount, y?
UA
x = 6.34y + 3,468
x = 15.47y + 891
B
y = 6.34x + 3.468
y = 15 47% + 891
C.
y = 6.34x + 3.468
y = 891X + 15.47
D
6 34x + 3.468y = 3.474.34
15.47x + 891y = 906 47

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x

As part of an annual fundraiser to raise money for diabetes research, diane joined a bikeathon. the track she biked on was 1,920 yards long. diane biked 38.5 laps. her sponsors agreed to donate an amount of money for each mile she biked. how many miles did she bike? first fill in the blanks on the left side using the ratios shown. then write your answer. given ratios: 5280ft / 1 mi , 1 mi /5280 ft , 1,920 yards / 1 lap , 1 lap / 1,920 yards , 3 ft / 1 yard , 1 yard / 3 ft. blanks: 38.5 laps / 1 yard x (blank) x (blank) x (blank) = (blank) miles i'm really confused on how to do this, and the explanations aren't exactly . if you could walk me through how to do this, it would be greatly appreciated.
