Gosh, I've done this problem before. Let's start with 13. In this problem, we're basically just skip counting. For example, in the roses row, in the second bouquet, we know we have to add 4 more flowers, so we can document 8. Continue to skip count for both. For 15, we would have about 96 more movie posters remaining, making our ratio 96:x. So, 96:x = 120:100. Therefore, x would equal 80- as 96:80 equals 120:100. If she needs 80 and already had 100, she should sell 20 posters. Hope this helped.
Answer:
2
Step-by-step explanation:
Divide by 4 on each side.
4x/4 and 8/4
Now we have just x on one side and 2 on the other.
So, x = 2.
Answer:
x=-1 y=4 (-1,4)
Step-by-step explanation:
For a non-resident:

For a resident:

We want to know the number of days
such that the two costs are equal ie 
To do this set the two costs equal to each other:


And solve for d:




The costs will be equal when a resident and a non-resident each use the beach for 12 days.
The non-numeric pattern that shows the pattern of Luke's lunch for two weeks is P B P B P P B P B P
<h3>What are patterns and sequence?</h3>
Patterns are simply the rules that guides the formation of a numeric or non-numeric sequence
From the question, we have the following highlights
- Pack lunch (P): Mondays, Wednesdays, and Fridays.
- Buy lunch (B): Tuesdays and Thursdays,
Using the above representation, the non-numeric pattern that shows the pattern of Luke's lunch for two weeks can be represented as P B P B P P B P B P
