Joseph rode the roller coaster 15 times.
Because - 9 - 6 = 3 x 5 = 15
A) 3 9/20
b) 4 3/20
c) 3 8/15
d) 6 1/15
e) 8 1/21
f) 8 11/21
g) 18 33/40
h) 21 1/40
1). Two factors of -48 => x * y = -48
=> the absolute values of the two numbers may be:
48 and 1
24 and 2
16 and 3
12 and 4
6 and 8
2). Have a differencie of 19 = > x - y = 19
That makes that the numbers be + 16 and - 3
Because (+16) * (-3) = - 48
And +16 - (-3) = +16 + 3 = 19.
3) The sum of the factors is +16 + (-3) = 16 - 3 = 13.
So the answer is the option C. 13.
