Y = 7x, if x equals the number of hours and y equals the amount of money charged.
Answer: The answer is {(0,0)} !
Step-by-step explanation:
Answer:
first he had M some unknown amount
then he had 2/3 M since he spent 1/3 M
then he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)
then he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M
and check by doing each step and figuring how much was spent and how much left.
<u>another</u><u> </u><u>method</u><u> </u>
let us consider the left amount be Y and total now of M dollar be X
then
Y = amount of money Nartin has left
Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20
Y = X - 1/3 X - 3/4 X + 3/12 X - 20
Y = X - 4/12 X - 9/12 X + 3/12 X - 20
Y = X - 10/12 X - 20
Y = X - 5/6 X - 20
Y = ( 1 / 6 ) ( X ) - 20

Answer:
He lead the race for 1.5 miles
Step-by-step explanation:
4 tenths is equal to 4/10 = 0.4
0.4*2.5 miles = 1 mile
Lenox took the lead after the first mile of the race.
Se he lead the race for
2.5 miles - 1 mile = 1.5 miles
Which is equal to 60% of the whole trajectory.
I think it would be 70% but I don't know for sure
I hope this helps you!
