We have to find what 20% of $1,800 is. 

We can do this by multiplying 0.20 and $1,800
Lets do that :)

0.20 x $1,800 = $360 

Now we know that 20% of $1,800 is $360 

Since it is asking for his new salary with an extra 20%
we add $1,800 and $360  

Soo..
$1,800 + $360 = $2,160 

This means that mark's new paycheck is $2,169 

Good Luck! :)

Answer:

\boxed {m = -\frac{5}{7}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to determine the slope of two given points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

First Point: (x_{1} , y_{1})

Second Point: (x_{2}, y_{2})

-Substitute both points:

First Point: (5, 11)

Second Point: (19, -1)

m = \frac{-1 - 11}{19 - 5}

-Solve for the slope:

m = \frac{-1 - 11}{19 - 5}

m = \frac{-10}{14}

\boxed {m = -\frac{5}{7}}

Therefore, the slope is -\frac{5}{7}

Musya8 [376]

The number of purple marbles in the bag are; 201 purple marbles

<h3>How to work out fraction of bar model?</h3>

We are told that Two-fifths of the marbles are green, and the rest are purple.

A) The image attached shows the bar model where the shaded parts denote the purple marble while the unshaded parts denote the green marbles.

B) We are told that there are 134 green marbles.

If the total number of marbles are x. Then;

(2/5)x = 134

x = 134 * 5/2

x = 335 marbles

Thus;

Purple Marbles = (3/5) * 335 = 201 purple marbles
