Answer:

A. 2/3

Step-by-step explanation:

Fraction is another way to divide , So in some math problems they want you to either flip the fraction or divide the numbers .

Option A is correct, the expression 2÷3 written as a fraction is 2/3.

A fraction represents a part of a whole.

We have to write  2÷3  as a fraction.

Two divided by three.

We have to split the number two by three parts.

We know that any division expression can be written as a fraction, the numerator is a part and denominator is a whole.

Two is the numerator and three is the denominator.

The numerator represents the part and three represents the whole.

This we can write in fraction as 2/3.

Two by three is the fraction form of two divided by three.

Where as [tex]3\frac{1}{2}[/tex], is not a fraction, it is a mixed number.

3/2, is not equivalent to 2 ÷ 3, it represents the fraction one and a half and [tex]2\frac{1}{3}[/tex] is not equivalent to 2 ÷ 3, it represents the mixed number two and one-third.

Hence, Option A is correct, the expression 2÷3 written as a fraction is 2/3.

Step-by-step explanation:

Answer:

x = -3

y = -6/5

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x.

2x + 5(0) = -6

x = -3

Find the y-intercepts.

To find the y-intercept(s), substitute in 0 for x and solve for y.

2(0) + 5y = -6

y = -6/5

good luck, i hope this helps :)

Answer:

sry I don't know.

if someone answer tell me the answer I also want to know : )

Answer:

There are 153 combinations

Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)

= 18 * 17 / 2 = 153

OK that is the maths - now the explanation

The first sock can be any of 18

The second sock can be any of 17 (one already been selected and they must be mismatched)

Therefore there are 18*17 = 306 permutations she could make

However the question asks for "combinations" not "permutations"

A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.

Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153

FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!
