Complementary angles are angle pairs whose measures sum to one right angle (14 turn,90°, or π2 radians)
B.
Let's simply look at each conjecture and determine if it's true or false.
A. 2n– 1 is odd if n is positive: Since n is an integer, 2n will
always be even. And an even number minus 1 is always odd. Doesn't matter
if n is positive or not. So this conjecture is true.
B. 2n– 1 is always even: Once again, 2n will always be even. So 2n-1 will always be odd. This conjecture is false.
C. 2n– 1 is odd if n is even: 2n is always even, so 2n-1 will always
be odd, regardless of what n is. So this conjecture is true.
D. 2n– 1 is always odd: 2n will always be even. So 2n-1 will always be odd. Once again, this conjecture is true.
Of the 4 conjectures above, only conjecture B is false. So the answer is B.
Just set them equal to each other
2x-2= x+3
2x-5=x
-5= -x
X=5
Hope it helps
Answer:
3h
Step-by-step explanation:
let time be x
total distance = 450
75x+75x=450
150x=450
x=3h
