Let x represents the numbers of hours that Billie and Toni are driving after first day and ‘Y’ represent the distance they have passed distance
Y=420+65
And, first day they traveled : 410 mi
2nd day they traveled =65.8=520 mi
3rd day they traveled =65.8=520
By the end of the third they traveled= 420+520=520
1460 mi
A quarter past two means 2:15. So if it took her 25 minutes to get there, the latest she could leave would be 1:50.
Replace the x in 7x by (3x + 1):-
(f o g)(x) = 7 * (3x + 1)
= 21x + 7 which is choice D.
2s + 3 = 19
2s = 16
s = 8
