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.

Answer: x = -4
Step-by-step explanation:
1/2 * (x - (-6)) = 1
distribute
1/2x + 3 = 1
isolate the variable
1/2x = -2
x = - 4
The formula for the volume of a rectangular prism is: l*w*h (length*width*height)
Since the Base area of a 3D figure is always the length times width of the bottom face, all we need to do to find the volume is multiply the Base area by the height.
173.6 (9) = 1562.4 cubic cm
Explanation:
The equation for this problem can be modeled in y = mx + b form.
m represents the rate of change and b represents the initial value or constant.
y = 10x + 20
x represents the number of hours he spent delivering newspapers
y is his total money after whatever number of hours he worked
The rate is 10, because it determines how much money he earns for each hour.
The y-intercept is 20, representing the starting amount of money in his bank account.
