Which is true when you rent ?
Delvig [45]

Answer:

As the question is not clear, as it is not stated that for whom this is true - for the owner or the person who rents the house.

Explanation:

With respect to the owner, the second option is correct. The owner is responsible for all the repairs and maintenance costs.

When you are the one who takes a house on rent or when you are a tenant, then you pay fewer upfront cost.

six times jasons collection of books and one-third of nathans collection add up to 134 books one-third of jasons collection and
atroni [7]
6j + 1/3n = 134...multiply by 3....18j + n = 402
1/3j + n = 31....multiply by 3....j + 3n = 93

the multiplying by 3 is optional...I just did it because it is easier to work with equations when there are no fractions.

18j + n = 402....multiply by -3
j + 3n = 93
----------------
-54j - 3n = - 1206 (result of multiplying by -3)
j + 3n = 93
----------------add
-53j = - 1113
j = -1113/-53
j = 21

j + 3n = 93
21 + 3n = 93
3n = 93 - 21
3n = 72
n = 72/3
n = 24

so Jasons collection (j) consists of 21 books and Nathans collection (n) consists of 24 books
