(08.06 lc)variable c is 9 more than variable w. variable c is also 3 less than variable w. which pair of equations best models the relationship between c and w?
c = w − 9
c = 4w + 3

c = w + 9
c = w − 3

w = c + 9
w = c − 3

w = c − 9
w = 4c + 3

To complete your spring schedule, you must add calculus and physics. at 9: 30, there are three calculus sections and two physics sections; while at 11: 30, there are two calculus sections and three physics sections. how many ways can you complete your schedule if your only open periods are 9: 30 and 11: 30?
