Answer:
The answer is D. 
Step-by-step explanation:

simplify the expression by multiplying

calculate the product

express with a positive exponent using 
1.5 hours=90 minutes
Because 90 minutes/ 30 minutes is 3, multiply 3.6 miles by 3 and get 10.8 miles as your final answer
Okay, let's see...
The problem is asking for a linear equation most likely in the form of y=mx+b
y is another way to say f(x)
<em>m = slope </em>
<em>b = y intercept </em>
Let's start with the y intercept first.
Y intercept means ' When does the line touch (intercept) the y axis.
In this case, if you look at the graph, the line <em>touches </em>the y axis at -1.
-1 will replaces b
To find the slope we are going to take 2 precise points from the graph.
Lets use <em>(0,-1)</em> and <em>(-6,4) </em>
To find the slope, we're going to use 
4 - (-1) / -6 - 0
Solve, our slope is 5/-6
That is our m
Our final equation is

Answer:
The answer is D if you forgot the 3 between the = sign and the + sign
Step-by-step explanation:
I just did 12 x p + 3 = 99
You have to do this because 12 times the amount of jerseys ordered (p) plus the 3 dollars of extra shipping cost. That equals 99.
It would be $2.6 (or $2.60) per pound.
