Can you help me with this question plzz?​
Dominik [7]

Answer: The answer is 96 wizards.

Step-by-step explanation:

So what I like to do is fraction formatting.

you start with x/blank \frac{blank}{120} and \frac{80}{100} you do cross multiply divide

and multiple 120 by 80(=9600) and divide by 100 (=96) because wizards are 20% less of the population than goblins, so they are equivalent to 80% of the goblins! Hope this helped!

*need to know in the next hour*
Genrish500 [490]

Answer:

20 blocks per pound

Step-by-step explanation:

We can see the line of best fit goes through the points (0, 0) and (5, 100).  WE will use these to find the slope:

m=\frac{y_2-y_1}{x_2-x_1}

Using our points,

m=\frac{100-0}{5-0}\\\\=\frac{100}{5}\\\\=20

This makes the slope 20 blocks per pound.
