Katelyn is training for a marathon. this week she ran 6 miles less than 2 times the number of miles she ran the previous week. she ran a total
of 42 miles in the two weeks.
which system of equations can be used to find the number of miles she ran this week, t, and the number of miles she ran the previous week,
o a. 1 = 2p - 6
a 1+p=42
a b
1p =42
o b. p=21-6
o
oc.
+p=42
1 = 2p +6
od. p=2+ + 6
od. += 42
