Answer:
i hope this helps
Step-by-step explanation:
the pH of the solution is 5.74.
1.50c + 2.50a = 1100
c + a = 500
multiply the second equation by -1.50
1.50c + 2.50a = 1100
-1.50c - 1.50a = -7.50
It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2
5x-5=4x+10
x=15
75-5=70
180-70=110
6y-4=110
6y=114
y=19
