What is 10 - 4 and 2/3?
Ymorist [56]
10 - 4 2/3

First, we convert mixed fraction into improper fraction.

4 2/3 = ((4*3)+2)/3 = 14/3

In subtracting fractions:
1) Both must have the same denominator.
10 is 10/1 and 14/3 have different denominators. 

2) Once they have the same denominator, then subtraction may be performed.

10 - 14/3 = 10 * 3/3 - 14/3 = 30/3 - 14/3 = 16/3

3) 16/3 must be simplified.

16/3 = 5 1/3

10 - 4 2/3 = 5 1/3

Which fractions are the same value as 16 divided by-3
iragen [17]

Answer:

Not sure if this was meant to be a multi choice question, but I'll try help anyway.

As long as you times the denominator and the numerator by the same number, many fractions can be of the same value as 16/-3.

For example, a potential answer to this could be 32/-6.

If we simplify this, we still get  16/-3.

They're different fractions, but of the same value.

Hope this helps!!

Liula [17]

Answer:

21.C

23.B

24.D

Step-by-step explanation:

Domain is x

Range is y

If you can find a relation between x and y, that relation is a function.

In 21,

I. y = 0.x +5

II. Nothing.

III. y = x

In 22,

15 birdhouses needed to be built, then domain is from 0 - 15

In 23,

Try to insert x in to f(x) you will find out f(x), for i.e : x = 0, f(x) = 0.10 x 0 +5 =5.
