3 miles per hour. Theres 4 hours between 9 am and 12 and another 6 from 1to 6.so ten hours. then 12.8 plus 17.8 thats 30 then 30 divided by ten is 3 miles per hour. Your welcome :)

(12.8+17.2)/((12-9)+(6-1))
30/(3+5)
30/8
15/4
3.75mph
It's been awhile since I've done this type of math but I hope I got it right.

Kristin poured 6 ounces of lemonade into each of 19 glasses. Exactly how many ounces of lemonade did Kristin pour into all these
andriy [413]

Answer:

114

Step-by-step explanation:

If Kristin poured it in 19 cups and your figuring out how many in total, you’d have to multiply. I did an area model, to solve this, and 10 x 6 = 60, 9 x 6 = 54. Then we add 60 + 54 and get 114 as our answer. (I calculated so I’m sure I’m correct)

First you had to add by seven from both sides of equation form.

-7+\frac{f}{2}+7=-1+7

Then simplify by equation.

\frac{f}{2}=6

Next, you multiply by two from both sides of equation form.

\frac{2f}{2}=6*2

And finally, simplify by equation.

6*2=12

2*6=12

12/6=2

12/2=6

f=12

Final answer: \boxed{f=12}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
