Answer:
6n=32
Step-by-step explanation:
Here you need to find the "unit rate," that is, the tuition cost per year:
<span>2 years of tuition costs about $7228 at pine tech. Write slope as cost per year (1 year)
Rise $7228
------ = ------------ = $3614 per year. This slope is POSITIVE, and the
Run 2 yr function for "tuition as a function of the # of years"
is linear and the relationship is proportional.</span>
Let the speed at which John is going towards Leakey = x mph
Time taken to reach Leakey = 4 hours
Distance = speed * time
So let the distance of Leakey from John's house be 4x ............. (1)
Speed while returning was 20 mph less = (x-20)
Time taken was= 7 hours
distance = (x-20)*7 ................(2)
As the distance remains the same, equation 1 = equation 2




So, the speed is
mph
Distance = 4x
= 
Hence, the distance of Leakey from John's house is 186.667 miles.
Yes. 5x-7y=2x-7
3x-7y=-7-3x
y=1+3/7x
y is the equation of the line where the y-intercept is (0,1) and the slope is 3/7.
4.8 pounds, set it up as 4 over ten times x over 12, 4 times 12 divided by ten equals 4.8
