Using something like desmos will give you the graphs.
The red graph is y = - 1/2 x +2
The blue graph is 6x + 3y = 6
The long side of an isosolies triangle
The first A because once you plug in the numbers into the x,y it is easier to find the solution.
Based on the fact that he added three correct questions, Levi is wrong in assuming that the ratio of correct answers to total answers remained the same.
<h3>Why is Levi wrong?</h3><h3 />
When the total number of variables being compared in a ratio changes, the ratio itself will change.
This means that Levi is wrong in assuming that the ratio of correct answers to total questions will remain the same after he added 3 questions to both measures.
The first ratio of correct answers to questions was:
8 : 10
4 : 5
After three correct answers are added, it becomes:
11 : 13
This is not the same as the first ratio of 4 : 5.

Addie's speed was 
Step-by-step explanation:
Given,
Distance walked by Addie = 
Time taken by Addie = 45 minutes
Converting the time into hours;
1 hour = 60 minutes
45 minutes = 
Distance = Speed * Time
Speed = Distance/Time
Speed = 
Speed = 
Speed =
