Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.
a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.
Answer:
Equation: y=(-1/20)x+12.
Slope: -1/20
Y-intercept: (0, 12)
Step-by-step explanation:
Let x=the number of gallons of gas in Christopher's car.
If we start with 12 gallons, we have the equation: y=(-1/20)x+12.
This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

Pls work it out for me I'm VERY confused.
I will be using * as the degree symbol
Answer:
a) 105*
b) 105*
c) 105*
Step-by-step explanation:
a) the car is facing west or left. If you imagine it spinning completely around to face east, it would be turning 180*. However it does not go that last 75* shown on the map. So 180 - 75 = 105
b) The angle diagonal to the 105* angle is also 105*. And since 3rd and 4th street are parallel so is the angle you are trying to find
c) This is the same turn as the first one but opposite

What is Arithmetic Mean?The simplest and most popular way to measure a mean or average is the arithmetic mean. It simply entails adding up a collection of numbers, then dividing that total by the total number of numbers in the series.
Given:
According to box plot the mean is
= (3 x 2+ 4 x 1 + 5 x 2 + 7 x 8 + 8 x 3+ 9x 5 + 10 x 5 ) / 26
= (6 + 4 + 10 + 56 + 24 + 45 + 50 ) / 26
= 195 / 26
= 7.5
Hence, the mean is 7.5.
Also, the median = (7+8)/2 = 7.5
