A right parenthesis       )       is missing from this problem statement.  I'm assuming that you meant

<span>3 1/2+( 2+4 1/2).

There are at least two ways in which you could do this problem.  One would be to simply drop the parentheses entirely:

</span><span>3 1/2+ 2+4 1/2                It'd make sense to add 3 1/2 and 4 1/2 together FIRST, and then to add 2 to the result.

Or, do the work inside the parentheses FIRST:  </span><span>3 1/2+( 2+4 1/2).
</span>
This simplifies the problem to    <span>3 1/2+( 6 1/2).

You MUST get the same answer either way.</span>

Step-by-step explanation:

This problem bothers on the use of mathematical properties

Given the expression

3 1/2+( 2+4 1/2)

Applying the associative property rule which says we can add or multiply regardless of how numbers are grouped

Associative property

3 1/2+( 2+4 1/2) can re re-written as

(3 1/2+2) +4 1/2

Commutative property

This rule states that the we can move (commute) figures about and still get same result.

Hence 3 1/2+( 2+4 1/2) can also be expressed as (2+4 1/2+3 1/2)

Or (4 1/2 +2+ 3 1/2)

On a number​ line, suppose point E has a coordinate of -4 ​, and EG = 13. What are the possible coordinates of point​ G?
Ludmilka [50]

Answer:

9 or -17

Step-by-step explanation:

Hello!

The distance can be positive or negative, as we are just counting the number of units they are apart.

To find the possible coordinates for G, we can add or subtract 13 from -4 to find the possible coordinates for G.

<h3>Find G</h3>
  • -4 + 13 = G1
    -4 - 13 = G2
  • 9 = G1
    -17 = G2

The possible coordinates of G are 9 or -17.
