It should be the first one, or 3x, I’m pretty sure because x is going to be the amount that he has and he has 3 times the amount or something
Answer:
You need a common denominator.
Step-by-step explanation:
3/4+2/3
9/12+8/12
Answer:
Obtuse
Step-by-step explanation:
Plugging the numbers into the Pythagorean Theorem (a^2 + b^2 = c ^2)
20^2 = 12^2 + 15^2
400 > 144 + 225
400 > 369
Because of the Converse of the Pythagorean Theorem, which tells us if c is greater than a+b, it is obtuse
Since they’re equal probability, 205/400 = 51.25%. There’s a 51.25%
Well if you use the subtraction method for elimination you get
2x+-2y=12
Now you can times one at a time by zero and find what each equals.
2(0) +-2y=12
y=-6
2x+-2(0)=12
x=6
