Answer:
the width is 9 23/30 feet ≈ 9.767 ft
Step-by-step explanation:
Let w represent the width of the train car. Then 6 times the width is 6w, and 8 ft less than that is (6w-8). We are told this amount is 50.6 feet, so we have ...
6w -8 = 50.6
6w = 58.6 . . . . . . . add 8; next divide by 6
58.6/6 = w = 586/60 = 293/30 = 9 23/30 . . . . feet
This is a repeating decimal: 9.766666...
The width of the train car is 9 23/30 ft, about 9.77 ft.
Answer:
The cost of apple juice per ounce is 20 cents.
Explanation:
We know that a
16
ounce bottle is
$
3.20
and we want to find how much per ounce is.
So we set up a proportion and let
x
be the cost of one ounce:
16
3.20
=
1
x
Now we can cross multiply:
16
x
=
3.20
Divide both sides by
16
:
16
x
16
=
3.20
16
Therefore,
x
=
0.20
The cost of apple juice per ounce is 20 cents.
Hope this helps!
Step-by-step explanation:
Answer:
w = 40 miles per hour
r = 300 miles per hour
Step-by-step explanation:
We add w with the wind and subtract w against the wind
r+w = 340 miles per hour
r - w = 260 miles per hour
Add the two equations together to eliminate w
r+w = 340 miles per hour
r - w = 260 miles per hour
----------------------------------------
2r = 600
Divide by 2
r = 300 miles per hour without the wind
Now find w
r+w = 340
300 + w = 340
Subtract 300
w = 340-300
w = 40 miles per hour
