X= -12.5 you add (4+3) then, you combine it with 18 to get 25, then you divide 25 by -2x
The last one

Answer:
44
Step-by-step explanation:
if she had 10 left at the end and you add the other half from lunch which is 12, then that gives you 22. Since before lunch she had half (22), all you gotta do is add the other half which is 22. 22+22=44 and that's your answer.
The area of the square is 4
and the area of the triangle is 2
4+2=6
the area is 6
Using the proportion given, there will be 57 catfish in the pond.
The proportion given to us is
5.7/20 = x/200
Cross multiply:
5.7*200 = 20*x
1140 = 20x
Divide both sides by 20:
1140/20 = 20x/20
57 = x
