Answer: C. |-4 - 3|
<u>Step-by-step explanation:</u>
x = -4
y = 3
The distance between them is the difference. The mathematical operation for difference is subtraction.
Distance is a unit of measurement. Measurements cannot be negative so the absolute value sign is used to ensure the difference is positive.
The question gives the relationship to be
![1in=21mi](https://tex.z-dn.net/?f=1in%3D21mi)
We will interpolate to solve the question.
First Question: 147 mi

Cross multiplying,
Answer:
2.64cm
Step-by-step explanation:
A = π r^2
5.5 = π r^2
1.75 = r^2
r = 1.32
Diameter is then 2(1.32) = 2.64
No, but 16/15 is equivalent
8? I mean its kind of a guess
