Answer:
34 Nickles 49 Quarters
Step-by-step explanation:
You have to give variables to the Quarters and Nickles (x and y)
Then you have to write corresponding equations based on the problem:
x+y=83
.25x+.05y=13.95
Then you would solve for y by isolating the x value in the first equation and plugging it into the second equation.
x=83-y ----> .25(83-y)+.05y=13.95
Solve for y
y=34
Then plug y into first equation to get quarters
Answer:
1.56x+10.15

Answer:
2281.38
Step-by-step explanation:
A=P(1+r/n)^nt
6000=P(1+0.08/12)^12*6
P=6000/(1+0.08/12)^72
P=3718.62
This P value is the money he started with.
6000-3718.62=2281.38
Luther earned 2281 dollars over 6 years.

I will be assuming that the equation will be linear since there are only 2 data points available. The form of the equation will be
c = aw + b
where
c = calories burned
a = some constant
w = weight
b = some other constant.
If you look at the equation, you'll notice that it looks like the equation for a line i slope intercept form. So first, let's calculate the slope of the desired equation.
a = (600-420)/(172-120) = 180/52 = 45/13 = 3.461538462
Now we have the equation
c = w*45/13 + b
Substitute the values for a known point, giving
420 = 120*45/13 + b
Now solve for b
420 = 120*45/13 + b
420 = 5400/13 + b
420 - 5400/13 = b
5460/13 - 5400/13 = b
60/13 = b
So now the equation is
c = w*45/13 + 60/13</span>
