The expression would be 9 + m = 45 so your answer would be 36 so m=36.
Answer: x = 8
BC = 13
AB = 13
AD = 10
Step-by-step explanation:
The figure shows that AB = BC so:
x+5 = 2x-3
2x-x = 5+3
x = 8
Hence we have:
BC = 2(8)-3 = 13
AB = 8+5 = 13
AD = 8+2 = 10
Given:
Total solution : 1000mL
Pure acetic acid = 26mL
To find:
The percent concentration of given solution.
Solution:
We know that,

Putting the given values, we get



Therefore, the percent concentration of this solution is 2.6%.
