Answer:
1 mile = 15 seconds
Step-by-step explanation:
3 minutes and 15 seconds = 3 min + 15 sec
1 minute = 60 seconds
15 seconds =15/60 = 0,25 min
then
3minutes and 15 seconds = 3.25 minutes
13miles in 3 minutes and 15 seconds
= 13 miles / 3.25 minutes
= 4 miles / 1 minute
every minute Jose ran 4 miles
then:
4 miles is a 1 minute
1 mile is a T minutes
T = 1*1/4
T = 1/4 minute
1 minute = 60 secomds
1/4 minute = 60*1/4 = 60/4 = 15 seconds
Well this is easyyy:) you just need to multiply 4 and 2/7 by 1/2
buttt before we set up our question lets get 4 and 2/7 as an improper fraction
2
4 ----
7
we do that by multipying the 4 and 7 and then adding 2 soo lets do that
4 x 7 = 28
28 + 2 = 30
look we have our numerator!! (the top number)
and we dont have to do anything to the numerator just keep it the same as 7 :) lets look at our new improper fraction
30
------
7
see now we can set up our problem:)
30 1
------ x -----
<span> 7 2
</span>now all we do is multiply across:)
30 1 = 30 x 1 = 30
------ x -----
<span> 7 2 = 7 x 2 = 14
</span>here is our new fraction
30
------
14
wait lets simplify it by dividing each number by 2
30 ÷ 2 = 15
------
<span> 14 </span>÷ 2 = 7
ahh this is better here is our simpified fraction
15
-------
7
or as a decimal it is 2.142857143
either one is the correct answer:)

MARK ME BRIANLIEST :)
=7x-x^2>8
0=7x-x^2-8
0= -x^2 + 7x -8
0=(x^2 + 8x)-(x - 8)
0=x(x + 8)-1(x +8)
0=(x-1) 0=(x+8)
x=1 x= -8
