Answer:

2 1/4 yards above sea level

Step-by-step explanation:

The midpoint elevation is the average of the endpoint elevations, their sum divided by 2. When elevation is below sea level, it is represented by a negative number.

(17 3/4 - 13 1/4)/2 = (4 2/4)/2 = 2 1/4 . . . yards above sea level

Solve the following equations:<br> a)<br> 4b = 20

Sidana [21]

B=5
You need to get b by itself on the left side. 4b is multiplying 4 to b. You need to the opposite when you want the variable by itself. You would divide 4 to each side. 4 cancels out on the b so it turns into b. Then 4 divided by 20 is 5. B=5

KengaRu [80]

Answer:

$12+17+y+z$ or $29+y+z$ .

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 $12+y+17+z$ .

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 $a+b=b+a$ .

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

$12+17+y+z$

We can simplify our expression as:

$29+y+z$ .

Therefore, our required expression would be $12+17+y+z$ or $29+y+z$ .
