The fraction of Bobby's sports cards are baseball or football from the given fractions is; 69/100

How to simplify Fractions?

We are told that Bobby's collection of sports cards has 3/10 baseball cards and 39/100 football cards.

Thus,

Total baseball and football cards = 39/100 + 3/10 = 69/100

We are told that the rest are soccer cards. Thus;

Herman horse trader bought a horse for $600 and then sold it for $700. The next day he bought it back for $800 and then sold it for $900. How much money did Herman make altogether?

Answers

The total amount of the profit will be $200.

What is a profit?

A monetary profit, particularly the distinction between the amount gained and the actual cost of purchasing, running, or creating anything.

The profit is given as,

Profit = Selling price - Cost price

Herman horse trader bought a horse for $600 and then sold it for $700.

Then the profit will be

⇒ $700 - $600

⇒ $100

The next day he bought it back for $800 and then sold it for $900.

Then the profit will be

⇒ $900 - $800

⇒ $100

Then the total amount of the profit will be

P = $100 + $100

P = $200

The total amount of the profit will be $200.

More about the profit is given below.

What's (negative 7) plus (positive 7) plus (negative 17) (adding positive and negative numbers)

Answers

The answer is -17

The negative 7 and positive 7 add up to 0. They are opposites which cancel out. Think of it like being 7 dollars in debt (negative 7) and that debt is fully canceled out by the positive amount of money (positive 7). Put another way, the negative 7 means you go down 7 while the positive 7 means you go up 7.

After the first two terms cancel to 0, the -17 is the only thing left. Adding 0 to any number keeps that number the same.

Final answer:

The sum of (-7) + (+7) + (-17) in mathematics is -17, because a positive and a negative number of the same magnitude cancel each other out.

Explanation:

In the field of mathematics, particularly in arithmetic, a positive number and a negative number can be added together. In this case, you're adding the numbers -7 (negative 7), +7 (positive 7), and -17 (negative 17).
Let's break it down:

  • Negative 7 plus positive 7 gives you 0 because a positive and a negative number of the same magnitude cancel each other out.
  • Then, add this result (which is 0) to negative 17. The result of this is -17.

So, the sum of (-7) + (+7) + (-17) equals to -17.
