HAI DRIVIS 350 MILES IN 4 1/2
HOURS. HOW FAST WAS HE
GOING IN MIES PER HOUR?

77.78 mph

Step-by-step explanation:

[1] So we know that someone is driving 350 miles and it takes / took them 4 1/2 hours. I am going to change 4 1/2 to 4.5 for the sake of making it easier.

[2] Miles per hour, is, as it says, miles per hour. Aka, (your time is almost always on the bottom / the y)

[3] So, that being said, to solve you will but 350 over 4.5 like this: which calcuates to arounddd 77.78!

(I hope this is correct, I was slightly confused by the wording. Have a nice day!)

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
