The <em>linear</em> function y = 3 · w - 1 represents the number of sea shells found in each week.
The speed of the <em>driven</em> gear is 180 rounds per minute.
<h3>How to use direct and inverse relationships to analyze situations</h3>
In the first problem we have an example of <em>linear</em> progression, in which the number of sea shells is increased linearly every week. After a quick analysis, we conclude that the <em>linear</em> function y = 3 · w - 1, a kind of <em>direct</em> relationship.
In the second problem, we must an <em>inverse</em> relationship to determine the speed of the <em>driven</em> gear. Please notice that the speed of the gear is inversely proportional to the number of teeths. Then, we proceed to calculate the speed:
If we know that , and , then the speed of the driven gear is:
The speed of the <em>driven</em> gear is 180 rounds per minute.

Using the subtraction operation, the number of purple bags is 3 more than the number of yellow bags.
<u>Amount of each color available</u> :
- Amount of purple color = 64
- Amount of Yellow bags = 48
- Amount of color in pound required per bag =
<u>Number of Purple bags</u> :
<em>Amount of color required per bag × Amount of purple color</em>
Number of purple bags =
<u>Number of Yellow bags</u> :
<em>Amount of color required per bag × Amount of Yellow color</em>
Number of yellow bags =
Now we find the difference between the number of Purple and Yellow bags :
Number of purple bags - Number of yellow bags
Difference = 12 - 9 = 3 bags
Therefore, there are 3 more purple bags than Yellow bags.

Answer:
a) -64
0
b) 5
- 5
Step-by-step explanation:
Up square: Multiply the numbers in the right square and left square and write the answer in the up square.
Down square: Add the numbers in the right square and left square and write the answer in the down square.
Left and right square: Factorize the number in the up square and check if it satisfies (add or subtract the factors) the number in the down square.
a) Up square: -64
8*(-8) = -64
Down square: 0
8 + (-8) = 0
b) Factorize (-25), in such a way that when we add we should get 0.
-25 = 5 * (-5)
5 + (-5) = 0
Right square: 5
Left square : -5
c) Right square: (-3)
-12 ÷ 4 = (-3)
Down square : 1
4 + (-3) = 1
