To calculate the distance between 2 points we will use the following equation:
![D=\sqrt[]{(x_2-x_1)^2-(y_2-y_1)^2}](https://tex.z-dn.net/?f=D%3D%5Csqrt%5B%5D%7B%28x_2-x_1%29%5E2-%28y_2-y_1%29%5E2%7D)
For this exercise we have the following data:

We plug the values into the distance equation and solve for the unknown Y
Answer:
B = 100
Step-by-step explanation:
25 + .05x = 20 + .10x
5 = .05x
100 = x
Answer:
400 miles.
Step-by-step explanation:
Gallons used = 16 - 4 = 12 gallons.
Miles driven = 12 / 0.03
= 1200/3
= 400 miles.
Answer:
Base 5
Step-by-step explanation:
We want to determine the base at which:
113 X 2 =231
We consider the last number of the result (231).
The base must be a number such that:
3 X 2 will have a remainder of 1.
3 X 2 = 6 = 5 Remainder 1
Therefore:
113 X 2 =231 in positive integral number base 5.
Answer:
x = 37
Step-by-step explanation:
Power Theorem: 10 x (10 + 26) = 8 x (8 + x)
360 = 8 x (8 + x)
8 + x = 45
x = 37
