Nigel is planning his training schedule for a marathon over a 4-day period. he is uncertain how many miles he will run on two days. one expression for the total miles he will run is 12+y+17+z. use the commutative property to write an equivalent expression.

or .

Step-by-step explanation:

We have been given that Nigel is planning his training schedule for a marathon over a 4-day period. He is uncertain how many miles he will run on two days. One expression for the total miles he will run is .

The Commutative Property of Addition states that we can add numbers in any order. For example a and b be two numbers.

According to Commutative Property of Addition .

Similarly, we can write an equivalent expression to our given expression as:

We can simplify our expression as:

.

Therefore, our required expression would be or .

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
