Answer:
450 - 30x
Step-by-step explanation:
Lourdes reads 30 pages in one day
Total pages in book = 450
The number of days is x.
Lourdes reads in x days = number of pages read in one day x number of days
= 30 x
Number of pages left after x days = 450 - 30x
Thus, the number of pages left after x days is 450 - 30 x .

Step-by-step explanation:
Answer: first one =109360044xy−36453348x−2, 2nd,=3037778998,last one,=1968480790
Step-by-step explanation:Evaluate for x=3x,y=6y−2
33x(2025186)(6y−2)−2
33x(2025186)(6y−2)−2
=109360044xy−36453348x−2
Evaluate for x=20,y=25
(3)(20)(2025186)(25)−2
(3)(20)(2025186)(25)−2
=3037778998
because 18 is by itself i just did Evaluate for x=18,y=18
(3)(18)(2025186)(18)−2
(3)(18)(2025186)(18)−2
=1968480790
