Which of these is the algebraic expression for "nine less than some number?" Fraction 9 over k Fraction k over 9 9 − k k − 9. MIDDLE

We have some number k and we take 9 from it to end up with k-9, which represents 9 less than k.

For example, if k = 12, then k-9 = 12-9 = 3. So 3 is nine less than the number k = 12.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
