Solve for x in X-2 (x=8)
Substitute X=8 into 3x - 6y =18 (24-6y=18)
Solve for y in 24-6y=18 (y=1)
X=8 and y=1
Answer:
5 hours
Step-by-step explanation:
The equation to solve this is 7.80h+35=74.
7.80 represents the cost per hour, h represents the number of hours, 35 is the reservation fee, and 74 represents the total money.
7.80h+35-35=74-35
7.80h=39
h=5
Answer:
d = t(.7)
Step-by-step explanation:
We can start by dividing the values on the right by the values on the left.
Starting with the first one, 7/10=.7
It gives us .7
To double check this we can use the second values, 10.5/15=.7
It gives us .7
and even if we still aren't sure we see the last value also gives us the same answer, 14/20=.7
This means that if we multiplied the time by .7 for any of the time values, we would get our distance values.
Hope this helps! :)
