Yes, since adding two like variables will always result in the same variable.(i.e. x+x=2x not x^2). Any expression with the highest variable being to the power of 1 (or just x) is ALWAYS a linear expression.
Answer:
1) Angle AOC + Angle COB = Angle AOB
Angle AOC = X
Angle COB = Y
putting in equation, we get
X + Y = AOB
2) Angle X + Y = AOB (proved above)
AOB = 90° ( given)
Angle X + Angle y = 90°
Angle X is the complement of Y
Whole number is are numbers like 0, 1, 2, 3, 4...... and so on
negatives, fractions, decimals, and irrational numbers are not whole numbers
so the whole number portion of the two numbers are <u> 5 and 418</u>
-77 and 7/20 is the answer simplified and without it being simplified you get -77 and 35/100
