I believe, if I'm not correct but I think the answer would be 8 minutes or less.. Considering the fact that the Harris Family left 12 minutes ahead and the Arlen family is Averaging 55 MPH.. Too the speed that the Arlen's are going make the time for them to catch up to the harris's shorter. The Arlen's are going 15 mph faster sooo.. Yeah.. Tell em if this helps! :D
The amount of material/ number of pillows made
16/12 = 4/3 = 1 1/3
So the answer lies between integers 1 & 2
29.98+ 6.44 = 36.42 (cost with out the discount)
36.42/3 = 12.14
Answer-
12.14
50 is 10 times as much as 500
The equation for a line is y=mx+b
m is the slope, so when a line is perpendicular to another line is has a slope which is an opposite reciprocal, so change the -1/2 (the slope of the other line) to 2/1 or just 2
so m=2
now you need to plug in the point they give you for x and y
y=mx+b
4=2(4) + b
simplify
4=8 + b
subtract 8 over
-4 = b
now that you know that slope (m) and the y-intercept (b) you can plug those two numbers into the original equation for the answer
y= 2x -4
