4/1 = 2/x...4 miles to 1 hr = 2 miles to x hrs
cross multiply because this is a proportion
(4)(x) = (1)(2)
4x = 2
x = 2/4 reduces to 1/2...so she can walk 2 miles in 1/2 hr (or 30 minutes)
To find the inverse, interchange the variables and solve for y
hope this helps!

Answer:
d = 1
Step-by-step explanation:
For the number to be divisible by 9, the sum of digits must be a multiple of 9. The sum of digits is ...
4 + 3 + 7 + d + 0 + 3 = 17 +d
The nearest multiple of 9 is 18, so we have ...
17 +d = 18
d = 18 -17 = 1
The value of d is 1.
