To answer your question very literally, the united states only elects one president per term! The president can only serve two terms and is then forced to leave office! But if you where asking how many presidents the U.S. has had, as of 2016 the U.S. has had exactly 43 presidents and 44 presidencies (one served a second term)
Answer:
9.1
Step-by-step explanation:
Solve your system of equations.
2x+y=1;4x+2y=−1
Solve 2x+y=1 for y:
2x+y+−2x=1+−2x(Add -2x to both sides)
y=−2x+1
Substitute (−2x+1) for y in 4x+2y=−1:
4x+2y=−1
4x+2(−2x+1)=−1
2=−1(Simplify both sides of the equation)
2+−2=−1+−2(Add -2 to both sides)
0=−3
