x+y=18897
x=y+673
2y+673 = 18897
2y = 18224
y= 9112
x = 9112+673 = 9785
9112 + 9785 = 18897
so one country is 9112 and the second country is 9785

The number of women teachers attending the lecture is 1.
Step-by-step explanation:
Denote the variables as follows:
<em>M</em> = men
<em>W</em> = women
<em>T</em> = teacher
The data provided is:
n (M) = 23
n (W) = 29
n (T) = 4
n (M ∪ T) = 24
Compute the number of men teachers as follows:


Compute the number of women teachers as follows:



Thus, the number of women teachers attending the lecture is 1.
0.05 because 5 is bigger than 4 plus 4 is negative
Step-by-step explanation:
5x^2 - 20x + 20 = 5x^2 - 20x + 20
5(x^2 - 4x + 4) = 5(x^2 - 4x + 4)
(5 + 5) (x^2 - 4x + 4)
