Answer:

\Huge \boxed{-2}

Step-by-step explanation:

The <em>sum</em> is the result from adding two or more numbers to each other.

-6 + 4 = - 2

-6 is the starting point on the number line.

4 is added to -6, so an arrow from -6 goes 4 units to the right of the number line.

The arrow stops at -2.

Answer:

-2

Step-by-step explanation:

So we want to find the value of:

(-6)+(4)

Simply add:

(-6)+4=-2

Thus, drop the word SUM on -2.

Further notes:

To use the number line to solve, first start by placing your point on -6.

Since we are <em>adding</em> 4 to -6, we move to the right. Thus, move from -6 four spaces to the right.

If you do so correctly, you will end up at -2, the same answer we acquired previously.

The three medals earned in the Olympics are the gold, silver, and bronze medals. In the 2014 Winter Olympics, the United States
marta [7]

Answer:

Let x be the number of silver medals.

As there were two more gold medals than silver ones, gold medals are x+2

We also know that the number of bronze medals was 4 less than the sum of gold and silver, so if there are x + 2 of gold and x of silver, there are x+x+2-4 of bronze.

Now, we can do an equation, as we know there were a total of 28 medals:

x + x + 2 + x + x + 2 - 4 = 28

And we isolate x:

4x = 28

x = 28/4 = 7

There were 7 silver medals, so there were 9 gold ones (7-2) and 12 of bronze (9+7-4).
