3 1/2 = 3.5
3.5 / 28 = 1 / x......3.5 miles to 28 minutes = 1 mile to x minutes
cross multiply
(3.5)(x) = (28)(1)
3.5x = 28
x = 28 / 3.5
x = 8 minutes <===

Answer:
The solution is x = 0, y = -2.
Step-by-step explanation:
5x - 3y = 6
6x - 5y = 10
If we multiply the first equation by 5 and the second by - 3 we get:
25x - 15y = 30
-18x + 15y = -30 Adding these 2 equations eliminates y, we get:
7x + 0 = 0
x = 0.
Substituting x = 0 in the first equation:
5(0) - 3y = 6
y = 6/-3 = -2.

(WORK SHOWN BELOW)
X/4 = 8
multiply both sides by 4 to get the value of x
x=32
