Answer:
First prime factorize the number:
25 = 5 × 5
75 = 3 × 5 × 5
Then find the GCF:
GCF(25, 75)
= 5 × 5
= 25

Step-by-step explanation:
9 months/6 months = 6 days /x days
9/6 = 6/x

Answer:
A. 3x+50 ≤ 100; 16 people
Step-by-step explanation:
If x represents the number of people at Berta's party, then the cost of food is 3x. Added to the $50 cost of room rental, the total charge Berta must pay will be ...
3x +50
She wants this to be at most $100, so her inequality is ...
3x +50 ≤ 100
Berta can solve this by subtracting 50, then dividing by 3.
3x ≤ 50
x ≤ 16 2/3
Since x represents a number of <em>people</em>, and it is not possible (or desirable) to have 2/3 of a person show up, the maximum number of people that can attend Berta's party is 16.
