Answer:
84
Step-by-step explanation:
x = number of girls
The total for boys is 2x * 81 and for girls it would be 90x
Therefore, the equation goes like this:
2x * 81 + 90x
Then simplify, and set to equal 3x...
3x = 252
Which is the same as
x = 84

Answer:
The % of of acid in solution = 63.88 ml
Step-by-step explanation:
The solution of acid and water = 351 milliliters
The % of of acid in solution = 18.2% of 351 ml
Or, The % of of acid in solution = 
× 351 ml
Or, The % of of acid in solution = 63.882 ml
Hence ,The % of of acid in solution = 63.88 ml Answer
Answer:
$48.5
Step-by-step explanation:
Given data
Number of purses= 14+2= 16
Cost of 14 purses= $50
Cost of 2 purses= $38
Let us use the weighted cost method
Mean cost = (14*50+ 2*38)/16
Mean cost = (700+ 76)/16
Mean cost = 776/16
Mean cost =$48.5
