Answer:
3.75
Step-by-step explanation:
4x+9=24
4x=24-9
4x=15
x=15/4
x=3.75
Step-by-step explanation:
d = z - 9
d = 10 - 9 ----> substitute
d = 1
So if the earth goes 18 miles per second you would multiply 18 and 60 since 60 seconds are in a minute. And that is 1,080 miles in a minute then times that by 5 and your answer is 5,400 miles in 5 minutes.
