What angels? You need to show a picture :)
<span>Distance = d miles ; rate = 60 mph ; time = d/60 hrs
distance = d miles ; rate = 50 mph ; time = d/50 hrs
----------------------
Round-trip DATA:
distance = 2d miles ; rate = 55 mph ; time = (2d)/55 hrs
-----------------------------------------------------------
Equation:
Roundtrip time - other time = -1/2 hr
(2d)/55 - [(d/60)+(d/50)] = -1/2
(2d)/55 - [(110d)/(50*60)] = -1/2
---
600(2d) - 11[110d] = -16500
1200d - 1210d = -16500
-10d = -16500
distance = 1650 miles
Hope this helped :)</span>
Cory brings five 1-gallon jugs of juice.
5 jugs * 1 gallon per jug = 5 gallons of juice total
Knowing that the cups Cory is using to serve can hold 8 fluid ounces, we are asked to figure out how many cups Cory can serve.
1 gallon = 128 fluid ounces
5 gallons = x fluid ounces
Let's set up a proportional equation.
1/128 = 5/x
Now, we can use cross products to simplify and solve.
1 * x = 128 * 5
x = 640 fluid ounces.
Therefore, Cory has a total of 640 fluid ounces.
To find out how many cups he can serve, we need to divide the total amount of juice he has (640 oz) by the amount of juice in each cup (8 oz).
640 / 8 = 80
Thus, Cory can serve 80 cups of juice at parent night.
Answer:
x=8
Step-by-step explanation:
7+5x
so basically what you have to do is take the 7 and subtract from both sides
so like this: 7-7 is 0 so that cancels then 47-7 is 40
then you take 5x and divide 40 by 5
so x=8
hope this helped!
