21d+.23x (d being per day) (x being every mile above 125)
Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
The answer would be: x+2y
First, combine the like terms.
-x and 2x
Now your equation looks like this:
x+y+y
Now combine the y like terms.
y and y and you get 2y
Then you are left with your answer: x+2y
Hope this helps! :3
Answer:
I'm gonna go a little out of order.
To determine b, find where the line crosses the <em>y</em>-axis. If it's positive, put it as " + " and if it's negative, put it as " - ".
To determine m, find two points on the line that are directly on the number. Example, choose (4, 1) instead of (4.1, 5.2). Go up/down and left/right (while making sure to count) until you reach the second number. going up and right will be considered positive while down and left are considered negative.
Using rise/run, put your number for up/down as a numerator over your left/right, which will be a denominator.
Insert <em>m</em> and <em>b</em> and you're good to go!
