Answer:
where's the number line??
Answer:
k = 10.39
Step-by-step explanation:
tangent 30 = opposite side / adjacent side, opposite side = 9, adjacent side = k + 3sqrt3.
tan 30 = 9/(k + 3sqrt3)
0.5774 = 9/(k + 3sqrt3)
k + 3sqrt3 = 15.5885
k = 15.5885 - 3sqrt3
k = 10.392
Well, nickles are only 5 cents. You knew that. Because there is nickles in the mix, the answer will be great. 3 Quarters. 7 dimes + 1 nickle. 2 Quarters, 2 dimes, and 1 nickle. 15 nickles. 5 dimes and 1 quarter. I think that is most of them.
4x + 160y = 120
and
1x + 240y = 80
that will be be the equations. if we multiply the bottom equation by 4 we get:
4x + 960y = 320
now subtract one equation from another:
4x + 160y = 120
-(4x + 960y = 320)
and get:
-800y = -200
y = $0.25
now plug this into one equation
x +240(.25) = 80
x + 60 = 80
x = $20
so $20 per day and $0.25 per mile
