Step-by-step explanation:
2x-y= -1
x-2y= -8
eqn2*2=2x-4y= -16
eqn3- eqn1
-3y=- -15 y=5
2x-5= -1
2x=4 x=2
Answer:
The green one
Step-by-step explanation:
In an obtuse triangle, one of the angles is greater than 90 degrees.
I would say since thats $1500+ a month about 600 dollars, because she will have bills and then have to buy food drinks and alot more.
Proof: square roots of prime numbers are irrational. the square root of any prime number must be an irrational number. For example, because of this proof we can quickly determine that √3, √5, √7, or √11 are irrational numbers.
moreover, √7= 2.645751311064590
This is an irrational. number
