9 3/4 = 39/4 mi/m
68 1/4 = 273/4 min
39/4 mutiply by 273/4 = 10647 / 16 mi = 665.4 mi
4x = 14y
y = 4/14(x)
y = 2/7(x) slope = 2/7
<span>-2x+7y=14
7y = 2x + 14
y = 2/7(x) + 2 slope = 2/7
parallel lines, slope is the same
both lines have slopes equal 2/7

X=1 is the answer to your question
-5/3, -0.1, 0.7, sqrt2, sqrt5
Y and x are the variables
