9.cassandra works at a bookstore. yesterday, she sold 18 hardcover books. the rest of the books she sold were paperback books. she sold a total of 41 books. how many paperback books did she sell?

use the variable p to represent the number of paperback books cassandra sold yesterday.

which equation represents this situation and its solution?

p + 18 = 41; p = 23

p + 41 = 18; p = 23

41p = 18; p = 23

18p = 41; p = 23

10.the table show the total distance d, in kilometers, a truck traveled after t hours.

time in hours (t) distance in kilometers (d)
0 0
1 100
2 200
3 300

which equation shows the relationship between d and t?

d=t+300

d=t+100

d=100t

d=300t
