Step-by-step explanation:
Hence, option A 85° is the correct answer.
X+y=8
2x^2-y=-5
elimination method means you link the 2 equations together to make one
these two already have y in the perfect form where you can cancel it out +y and -y so no need to perform any other action to a certain equation.. all you need to do is add them now
2x^2+x=3
Answer:
B
Step-by-step explanation:
all sides are the same
If x is how long your friend swims and y is how long you swim, the answer would be x + 15 = y
