Answer: t1 = -34; t2 = -64; t3 = -94
d is the distance between numbers (d > 0)
we have:
t5 = t1 + 4d = -154
t9 = t1 + 8d = -274
we have the equations:
t1 + 4d = -154
t1 + 8d = -274
<=> t1 = -34
d = -30
with t1 = -34 and = -30 => t2 = -34 - 30 = -64
t3 = -64 - 30 = -94
Step-by-step explanation:
Answer:
If the shelves are 4/5 full, then the total number of books in the library is 1,040 books
Step-by-step explanation:
13 roll of bookcases
All the bookcases have four shelves
Total number of shelves = 4 x 13
= 52 shelves
Each shelve holds 25 books each
Total number of books that can be in the shelves altogether = 52 x 25
= 1,300 books
If the shelves are 4/5 full, then the total number of books in the library is,
4/5 x 1300
= 1,040 books
1st one: since we are dealing with the same unit, months and aid cannot mix so this is wrong
2nd one: doesn't include the 2.59 so this is wrong
3rd one: includes both 70% and 2.59 so this is correct
4th one: this doesn't include a greater than sign > so this is wrong
the answer is the 3rd one
