If the question is how much Cody will jog to save ratio 4miles:3 miles
The ratio is $\frac{3}{4}$
We can just multiply 1 miles by ratio to see how much Cody will jog, so
$1* \frac{3}{4} =\frac{3}{4}$ miles
The result is $\frac{3}{4}$ miles

Answer:

B) identity property of addition.

Step-by-step explanation:

Given:

The statement given is:

$10+a=10,\ then\ a=0$

Here, we observe that 10 is added to a giving the number 10 itself as the answer. So, we know of a property which says that when 0 is added to a number, the result is the number itself. This property is called identity property of addition.

So, the value of $a$ must be 0 because on adding $a$ to 10, we are getting the number 10 only. So, the above statement is an example of identity property of addition.
