We do math problems today! (HB MA!)

Because it's Modern Algebra's birthday. :3






So, we all attempt to solve as many math problems as we can starting now, simply for his amusement as to how stupid some of us are. Go ahead and post your answers right here, and hopefully by the end of the day we'll be able to get every single one without any help from our resident human calculator. :3

Spoiler for:

1. In a triangle, the measures of the angles are x, 3x, and 5x. What is the measure of the largest angle?

2. Solve for x if 2x - 5 < 11 and x + 3 < 20.

3. If a number is added to one more than that number, and then one less than the original number is subtracted from the sum, the result is 21. What is the original number?

4. How many 3 digit numbers have no repeated digits?

5. If x2 + y2 = 100, and xy = 18, find the value of x - y.

6. In a triangle, the sum of two of the angles is equal to the third. If the lengths of the two longer sides are 12 and 13, what is the length of the shortest side?

7. A dog is inside a yard that is 100 feet by 100 feet. He is chained to one wall, at the midpoint of the wall. His chain is 100 feet long. What is the total area the dog is able to access inside the yard?

8. If f(x) = x3 + x2 - x, find all points where f(x) and its inverse intersect.

Also, happy birthday.

@Zylos - you're the best Furry friend anyone could have...
             here, I'll start with the first 3! ~(G

#@MA - thanks again for helping me with my scripts skills!

Screw the math, cut the cake!

Happy Birthday, MA!

What ^ he said.

HAPPY BIRTHDAY! :3

God I hate maths, my head hurts on Zylos' problems.

But 6+2 is 8.

Happy birthday modern <3

Happy birthday, MA!

Oh god, and I was wondering why was Algebra so hard today. XD

Congratulations :] may you live a wonderful year.

1. In a triangle, the measures of the angles are x, 3x, and 5x. What is the measure of the largest angle?
100 degrees

2. Solve for x if 2x - 5 < 11 and x + 3 < 20.
x < 8

3. If a number is added to one more than that number, and then one less than the original number is subtracted from the sum, the result is 21. What is the original number?
21

4. How many 3 digit numbers have no repeated digits?
567?

5. If x2 + y2 = 100, and xy = 18, find the value of x - y.
324/y2 + y2 = 100
324 + y4 = 100y2
324 = -y2(y+10)(y-10)
uh idk

6. In a triangle, the sum of two of the angles is equal to the third. If the lengths of the two longer sides are 12 and 13, what is the length of the shortest side?
5

7. A dog is inside a yard that is 100 feet by 100 feet. He is chained to one wall, at the midpoint of the wall. His chain is 100 feet long. What is the total area the dog is able to access inside the yard?
~7850 ft

8. If f(x) = x3 + x2 - x, find all points where f(x) and its inverse intersect.
no ;-;

My guesses inputted.

And HAPPY BIRTHDAY MA!

Screw the math, cut the cake!

Happy Birthday, MA!

haha, thanks guys. You got a few wrong though moo
