Answer:
B. 3
Step-by-step explanation:
16 : 4 = 12 : |GD|
4=12 : |GD|
|GD| = 12 : 4 = 3, Answer is B
Answer:
b=16
Step-by-step explanation:
1) Divide 3 on both sides.
2) 3 divided by 3 and 48 divided 3.
3) Now you're left with 16, so the value of b is 16.
Answer: it’s the first one.
Step-by-step explanation:
Answer:
x = 325 miles
Step-by-step explanation:

Let x% be the salt concentration of first solution.
Then in 8ml, amount of salt = 
Given that to this 8ml solution, 11ml solution of a 47% salt solution is mixed.
amount of salt in 11ml of 47% salt solution is
= 
So, total amount of salt in new mixture = 
But given that this new solution is a 43% salt solution.
Hence amount of salt in new mixture of (8+11)=19ml solution of 43% salt solution is 
Hence 
8x+517 = 817
8x=817-517 = 300
x= 300/8 = 37.5
Hence the salt concentration in the first solution is 37.5%
