Answer:

90, 540, and 190

Step-by-step explanation:

To write an equation or expression for the numbers, first define the variables.

The "first number" is x.

"6 times a first number" is 6x. This is the second number.

"100 more than the first number" is 100+x. This is the third number.

All together, they add to 820.

x+6x+100+x = 820

8x + 100 = 820

8x = 720

x= 90

So the first number is 90. The second number is 6x = 6*90 = 540. The third number is 100+x = 100+90 = 190.

I need Advice preferably from 10th graders and up.
Lera25 [3.4K]

Life Advice:

I, too have experienced a huge fall in my math grades. I'm currently in high school and I have maybe 2 assignments done in my entire school year of math. I have almost no problem with any other subject, I just can't <em>motivate myself to do math</em>. I have a hard time ever even considering catching up, and I personally do not know if I will.

You might have the same problem I do, which is just lack of motivation.

If I were you I would provide some sort of incentive to get yourself to do it more efficiently and better yet, more enjoyably. I also advise listening to music that can get you in a good mood. Both of these things have been a huge help for me to stay motivated in other classes, and they may even help you with math.

I would also recommend getting some kind of a personal tutor. A friend, a worker at school, one of your math teachers. Never feel embarrassed to tell them you're behind. People will almost always be understanding when it comes to helping someone learn something they're behind on.

For an incentive, think about something you might be able to buy with money from a job that you take outside of high school, like a car or a house, or a guitar.

I, personally, am going to get a really beat-up pickup truck if it lasts till the end of my school year.

I hope this helped!

Thanks!

Your friend in life,

~Steve
