Answer:
x =104
y=76
z=104
Step-by-step explanation:
Y and 76 are vertical angles and vertical angles are equal
y = 76
x and 76 form a linear pair and linear pairs add to 180
x+76 = 180
x = 180-76
x = 104
x and z are vertical angles and vertical angles are equal
z = 104
The setup looks like this:
0.4(10) + 4x = 0.3(14)
the 14 is the total amount of acid added.
4 + 4x = 4.2
4x = 0.2
x = 0.05 or 5 % acid solution
Answer:
13 books.
Step-by-step explanation:
