U move 12, then it will become 52-12=4w (do u know why it bcme -12? Bcz if you move positive it will become negative. And if you move negative, it will become positive) then it would b like this 40=4w and bring over your 4 become 40/4=w (its multiply so u bring over it become division) and the ans is 10. Hope you understand me:)) and u plot 10 on ur no. line :>

4. In the Department of Natural Sciences, 14 faculty members have a PhD, and 30 faculty
Dvinal [7]

Answer:

  8

Step-by-step explanation:

We can start by making the table below to show the given numbers (red) and to assign a variable (x) to <em>the number we want to find: female PhDs</em>.

By subtracting the female numbers from the totals, we can find the corresponding numbers of male PhDs and non-PhDs.

The number of male non-PhDs is twice the number of male PhDs, so we have ...

  2(14 -x) = 20 -x

  28 -2x = 20 -x . . . . eliminate parentheses

  8 = x . . . . . . . . . . . .add 2x-20

The number of female faculty with PhDs is 8.
