Answer:
Option C: 38 is p more than 25
Step-by-step explanation:
the equation 25 + p = 38
can be read as 38 is 25 plus p units, or similarly ;
38 is p units more than 25.
Therefore from the three sentences you are showing, only the last one (option C) is the correct one.
Divisors of 18 are 1, 2, 3, 6, 9, 18.
Divisors of 24 are 1, 2, 3, 4, 6, 8, 12, 24.
The largest number on both lists is 6. This is the GCF of 18 and 24.
_____
a) No. The number present must be a divisor of 6.
b) Yes. The number present is a divisor of 6.
c) The number present must be a divisor of 6.
d) Possible numbers present are 1, 2, 3, 6.
Answer: option a. A customer earns 1 free night per 10 nights stayed.
Explanation:
Building a table can help you:
x: number of nigths stayed ---------- f(x) = 1/x: number of free nights
10 --------------------------------------------- 10/10 = 1
20 -------------------------------------------- 20/10 = 2
30 -------------------------------------------- 30/10 = 3
40 -------------------------------------------- 40/10 = 4
Then, the pattern permits you to conclude that a customer earns 1 free night per each 10 nights stayed, which is the option a.
