Answer:
They partially dissocate in water ( first choice)
2(5x+4)+3(2x-1)
Use the distributive property for both sets of parenthesis:
2(5x+4) = 2*5x + 2*4 = 10x+8
3(2x-1) = 3*2x - 3*1 = 6x-3
Now you have:
10x+8 + 6x-3
Now combine like terms:
10x + 6x = 16x
8-3 = 5
The final answer is 16x+5
Answer: C = 14
Step-by-step explanation: You can assume the A is less than B, and if you just go down in numbers such as A=6 and B=7 (To solve A + B = 13), you will eventually get to A=5 and B=8. If you do B = 8 + C = 14 ( That you get after subtracting 8 by 22 ) You should get 22, and to proof check it, you do A + C which is going to be 5 + 14 and you get 19 thus proving that C = 14.
Answer:
6 (I believe so)
Step-by-step explanation:
9n-24=4n+6
9n=4n+30
5n=30
n=6
