-(x-3)=-x+3
First, distribute -1 to x and -3.
-x+3=-x+3
As you can see, both sides are equal. You can continue to simplify:
Add x to both sides to get rid of the variable.
3=3 or infinitely many solutions because x can equal any number and still be equal to the other side.
I hope this helps :)
answer:
yes, it is a right triangle
step-by-step explanation:
- remember: a triangle can only be a right triangle if it works with the pythagorean theorem
- therefore, we can plug in the numbers we have in the formula
- know the formula: a^2 + b^2 = c^2
- now, plug in
a^2 + b^2 = c^2
6^2 + 8^2 = 10^2
- the largest side is always the hypotenuse
- we have to see if both sides equal to the same value
6^2 + 8^2 = 10^2
36 + 64 = 100
100 = 100
- yes they are equal, therefore it is a right triangle
Basically, you are taking 90% of 2500.
90% of 2500 is 2250.
Then because 10% is added...
2250 x 1.1 = $2475
answer: $2475
