I got 11.4.



I used the distance formula subtracted 7 from -4 and squared it and got 121 and then subtracted -8 from -5, two negative equal positive. Squared it and got 9. Added them together then found the square root. I could be wrong though since someone else got a different answer. You can try out the problem yourself to check over.

Allushta [10]

Answer: 1st train = 364 mph, 2nd train = 356.2


Step-by-step explanation:

Train 1: x + 7.8

Train 2: x

Train 1 + Train 2 = Sum

x + 7.8 +     x      = 720.2

           7.8 + 2x = 720.2

                    2x = 712.4

                      x = 356.2


Train 1: x + 7.8

 = 356.2 + 7.8

 = 364

A recipe for sparkling water juice calls for 1 1/2 quarts of sparkling water and 3/4 quart of grape juice
Alexxx [7]

Answer:

You would need 18 quarts of sparkling water to mix with 9 quarts of grape juice

Step-by-step explanation:

1 1/2 ---------> 3/4

x --------------> 9

We clear the value of x:

x = ((9) / (3/4)) * (1 1/2)

Rewriting we have:

x = ((9) * (4/3)) * (1 1/2)

x = (36/3) * (1 1/2)

x = (12) * (1 1/2)

x = (12) * (3/2)

x = 18
