Answer:

Explanation:

Just so you understand more deeply. There is more than one answer for this question, "as it is written". Math can be like this sometimes. And it can cause a lot of confusion. You must read it very carefully. If you multiply 8 x 4 you get 32. You know that (? x 7) must be greater that that number because you subtract (? x 3). If you multiply 5 x 7 you get 35. And that is greater than 32. Then take 32 from 35 to get 3. So that (5 x 7) - (1 x 3) also gives 32. If ? is assumed to be the same value for both (? x 7) and (? x 3). Then the problem can be solved by the rules of algebra, as it was done by Vivian. Any other analysis can give you other possible answers. If this is the case, then there must be some more to the question. You are not told that ? = ?. But this must be the case. And ? is an "operator", not just a question mark. To get just one answer, they must both be 8. You just use the "math rules" to move things around until you find the way to the answer. Scientists sometimes do this for months or years to solve complicated problems.

Often, your number sense gets confused by this kind of "discrepancy" or not knowing where to start situation, when you go beyond simple math and into algebra concepts. And this can leave you lost and not knowing where to start. If the general question is put to you to solve the problem by algebra concepts. You can assume more into the question by applying the rules of algebra. In algebra, symbols are used instead of numbers. This is part of the "math rules". Then the other rules are used to find the answer. The symbol ? is just as valid as x or y or whatever. In science you sometimes even use words. (That is how word problems are built.) Once you know the "math rules". You can apply logic to solve math problems.

I send this answer to give you a deeper understanding of what you are doing. You are learning basic rules now. Knowing what is causing your confusion can make things easier in the future. Jut play with the "ok" math maneuvers (+, -, multiplication, division) until you can do them without thinking. And math will become easy. There are more "math rules" that you will learn later. You will "see" the answers easier later. After you get more experience. Don't expect this now. The key to easy math is practice.

krok68 [10]

The first and most obvious answer to the question of why we're so obsessed with burgers is: burgers are cheap. ... It's not just that burgers are cheap, it's that they're easy to eat. Because the meat is ground up, you don't have to do much chewing. Because it's served on a bun, it's easy to eat.

Anyone pls do answer these asap!!!!will mark brainliest

Sonja [21]

Answer:

1.) Ugly debt, taking out a loan to buy something that's deprecating to your funds, responsibilities of being a car owner it can snowball you into a financial hole.

2.)Good debt, taking out a loan as an investment in the hopes of creating wealth with the job.

3.) Ugly debt, already in debt, you have to deprecate yourself financially by making shoe, lol, payments over time which reaps you nothing but more debt.

4.)Bad debt, something you buy that does nothing but hurt your funds. The pony alone is a horrible purchase.

5.) Good debt, investing in something that will create wealth in the future. Think student loan debt.

Explanation:

These "official" defintions will help you in the future recognizing these financial burdens. In my opinion, all debt is bad debt.

Debt is tricky. Though it’s an extremely useful financial tool many people depend on, it can be very dangerous when used improperly or carelessly. Here’s a quick rundown of the different roles debt can take on:

The (Sort Of) Good

Many responsible people use debt to acquire big-ticket items they need today, but that cost too much to pay for all at once. The vast majority of the population couldn’t afford a college education, vehicle, or home without financing them.

The Bad

Credit cards or other forms of borrowing can make it easy to forget that you’re playing with real money. It can cause people to buy things they don’t really need or make purchases they can’t really afford. Don’t take on debt without giving it some serious thought first.

The Ugly

Debt has a way of spiraling out of control—fast. Before you know it, your payments can total more than you can comfortably pay and there’s no end in sight. Think a payday loan might fix the problem? Think again. These “short-term,” high-rate loans are the very definition of ugly. Avoid them at all costs.
