Elanso [62]

Answer:

\displaystyle \frac{8}{18} = \frac{4}{9}\ ,\  \displaystyle \frac{12}{27} = \frac{4}{9}

Step-by-step explanation:

<u>Equivalent Fractions</u>

Two fractions are equivalent if they represent the same rational number, regardless of their expression. For example, the fraction 2/5 is equivalent to 10/25 since they both represent the number 0.4

To find if a given fraction is equivalent to another given fraction, we can simplify or amplify it until an equivalence is found or not. We can also simply perform the division and compare the results.

We must find out if the four choices are equivalent to the fraction 4/9. Let's start with the first one

\displaystyle \frac{20}{36} =\frac{5}{9}

We simplified it by 4 and found it's not equivalent to 4/9. The fraction

\displaystyle \frac{8}{18} = \frac{4}{9}

is equivalent to 4/9 when simplified by 2.

\displaystyle \frac{24}{45} = \frac{8}{15}

This fraction was simplified by 3 and is not equivalent to 4/9. Finally

\displaystyle \frac{12}{27} = \frac{4}{9}

Is equivalent to 4/9 when simplified by 3. Summarizing, these fractions are equivalent to 4/9

\boxed{\displaystyle \frac{8}{18} = \frac{4}{9}\ ,\  \displaystyle \frac{12}{27} = \frac{4}{9}}

Use slopes and y-intercepts to determine if the lines -3x – 3y = 1 and -3x – 4y = 5 are parallel.
N76 [4]

Answer:

they are not parallel

Step-by-step explanation:

Given the equations -3x – 3y = 1 and -3x – 4y = 5

Get the slope of each line

REwrite in the form y = mx+c

For the line -3x-3y = 1

-3y = 3x + 1

y = 3x/-3 + 1/-3

y = -x - 1/3

Slope m = -1

For the line -3x - 4y = 5

-4y = 3x + 5

y = -3/4 x - 5/4

Slope of the line is -3/4

Hence since both lines have different slopes, they are not parallel
