Answer:
Barney 145 3 Days 310 Miles
Mary 250 5 Days 600 Miles
A) 3 D + 310 M = 145
B) 5 D + 600 M = 250
Multiplying A) by -5/3
A) -5 D - 516.6666M = -241.66666666
B) 5D + 600M = 250
Adding A) and B)
83.3333 M = 8.3333333333
M = .10 per mile
3 D = 114
Daily Rate = 38 dollars per day
Step-by-step explanation:
Answer:
x=12
Step-by-step explanation:

And there is the answer. Sorry I couldn't explain better Im really not feeling good today
I don't understand it. Explain more.
Answer:
y=2.50x+20
Step-by-step explanation
Slope intercept equation is = y=mx+b
So you BEGIN with 20, which is your membership fee (it only gets charged once) then your mx is your slope. 2.50 is your slope because they earn 2.50 for each (x) video rented.
you place a number beside the x for each video rented. For example, if you rent 2 videos then you write this y=2.50(2)+20
To find the unit rate<span>, divide the numerator and denominator of the given </span>rate<span> by the denominator of the given </span>rate<span>. So in this case, divide the numerator and denominator of 70/5 by 5, to get 14/1, or 14 students per class, which is the </span>unit rate<span>.</span>
