The 3rd equation, as if you solve for x as shown, you will end up with equation x=8.




Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)
Now, we know,
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55
Here m represents the slope of graph which is nothing but rate of change of distance.
In short, option A will be your answer.
Hope this helps!
The mixed number is a fraction so the question is not able to be solved.
Hope this helps.
Here are the coordinates :)
Answer:
Division. The niece can divide both sides of the equation by 19 to find the answer.
Let me know if this helps!
