using the numbers 3, 5, and 8, can you write nine proper fractions and nine improper fractions? You may use each number only onc
Bond [772]

Answer:

First, we can write a fraction as a/b

Where a is the numerator, and b is the denominator.

A proper fraction is a fraction where the numerator is smaller than the denominator.

Using only the given numbers (only once per fraction), some examples of proper fractions are:

3/5

3/8

5/8

3/85

3/58

5/83

5/38

8/35

8/53

You can see that in all of them the denominator is larger than the numerator.

The improper fractions are those where the numerator is equal or larger than the denominator.

The 9 examples using the given numbers are:

5/3

8/5

8/3

35/8

38/5

53/8

58/3

83/5

85/3

Write in function form <br> 5x + 4y = 20.
xenn [34]

Answer:

Step-by-step explanation:

5x + 4y = 20

You need to express y in terms of x.

isolate the y term

4y = -5x + 20

divide both sides by the coefficient of y

y = (-5/4)x + 5

f(x) = (-5/4)x + 5

Plot the following radian measures on the given unit circle
son4ous [18]

By our very goofy system the circle constant \pi denotes half a circle, 180^\circ. So the conversion factor from radians to degrees is


\dfrac{ 180^\circ}{\pi}


\dfrac{\pi}{3} \times \dfrac{ 180^\circ}{\pi} = 60 ^\circ


Calling the rightmost dot [1] and counting counterclockwise, that's dot [4].


\dfrac{2\pi}{3}  \times \dfrac{ 180^\circ}{\pi} = \dfrac{2}{3} \times 180^\circ = 120^\circ


That's dot [6]


\dfrac{4\pi}{3} \times \dfrac{ 180^\circ}{\pi} = \dfrac{4}{3} \times 180^\circ = 240^\circ


That's dot [12]


\dfrac{5\pi}{3} \times \dfrac{ 180^\circ}{\pi} = \dfrac{5}{3} \times 180^\circ = 300^\circ


That's dot [14]
