Answer:
5/34 mi/min
Step-by-step explanation:
To find miles per minute, divide miles by minutes:
(7 3/4 mi)/(52 7/10 min) = (31/4 mi)/(527/10 min)
= (31/4)(10/527) mi/min = 310/2108 mi/min = 5/34 mi/min
Carlton's average pace was 5/34 miles per minute.

Since the given numbers are mixed numbers, we assume this is supposed to be a problem in fractions. Hence we have given the answer as a fraction. Its decimal value is about 0.14706. It is a repeating decimal with a 16-digit repeat.
You may have to do a little work to reduce the fraction 310/2108 to 5/34. You have to factor out a factor of 62. The numerator is 310=2·5·31, so that gives you a short list of factors to try with the denominator.

Answer:
Step-by-step explanation:
y - 3 = (-1/2)(x - 2)
Solve 8x-4y+9=0 for y so as to find the slope of this given line:
8x + 9 = 4y, or y = 2x + 9/4. The slope of the given line is 2. The slope of any line perpendicular to this one is the negative reciprocal of 2, which is -1/2.
Use the point-slope formula: y - k = m(x - h ). (h, k) is (2, 3) and m is -1/2.
Then we have: y - 3 = (-1/2)(x - 2)
