Rosie, Steph, and Terri are sisters. Rosie is the oldest and Terri is the youngest. The sum of the three girls' ages is 25. Rosie's age is 5 less than the sum of Steph's and Terri's ages combined. Terri is only 3 years younger than Rosie. What system of equations could be used to determine the three sisters' ages?
r + s + t = 30
( s + t ) - 5 = r
r + 3 = t
r + s + t = 25
( s + t ) - 5 = r
r - 3 = t
r + s + t = 25
s + t + 5 = r
r - 3 = t
r + s + t = 20
r - 5 = s + t
r + 3 = t

In a recent academics meet, 10 students from our school placed in their events, earning a total of 21 points. Each first place earned 3 points, each second place earned 2 points, and each third place earned 1 point. The number of second place finishers was the same as the number of first place finishers and third place finishers combined. Which of the following equations would be incorrect when writing a system of equations to determine the number of competitors that placed first (f), second (s), and third (t) ?
3f + 2s + 1t = 21
s = f + t
f + s + t = 10
f = s + t
