Mathematics
1 answer:
Bezzdna [24]3 years ago
8 0

Answer:

1.  The correct answer is B. <em>N</em>

3.  The answer is C.) Associative Property of Addition

Step-by-step explanation:

1.  Since - \frac{\sqrt{64} }{2}  = -4 , then it means that -4 cannot be a natural number (<em>N</em>). By definition, natural numbers ( <em>N </em>) are counting numbers that are positive integers.

3. According to the Associative Property of Addition:

   (<em>a</em> + <em>b</em> ) + <em>c</em> =  <em>a </em>+ (<em>b </em>+ <em>c </em>)

  This definition matches your test question, "(7<em>a</em> * 2b) + 3c = 3c + (7<em>a</em> * 2b)"

Hope this explanation helps :)

Marcus is skiing. He is 869 1/10 get up the mountain. He descends to 450 7/10 feet. What is his change in elevation
MatroZZZ [7]

Answer:

418 4/10

Step-by-step explanation:

To answer this we subtract 450 7/10 from 869 1/10.

We must borrow a '1' from 869 1/10:  868 11/10

Now subtract 450 7/10 from 868 11/10:

418 4/10 (CHANGE IN ELEVATION)

This reduces to 418 2/5.

VladimirAG [237]
Use Subtraction

1. Subtract
x+2y=7
3x-2y=-3
-------------
4x+0y=4 SIMPLIFY 4x=4

2. DIVIDE

4x=4
x=1

Substitute that into either of the original equations to get x=1, y=3
