For this case we can define the following variable:
x: unknown number
We write the equation that models the problem:

From here, we clear the value of x.
We have then:

Answer:
Completing the sentence we have:
0.04 is 1/10 of 0.40
Answer:
The answer would be C)5
Step-by-step explanation:
The unknown triangle is half of the size of the original triangle, The right side measurement basically hints to the actual answer.
construction of an angle bisector
of 60° into 30°and 30°
Answer: x = 0
Step-by-step explanation: so x = 0 is the equation of the vertical asymptote, and 0 must be left out of the domain: (−∞,0)U(0,∞) in interval notation.
Answer:
Step-by-step explanation:
Final concentration % = [grams of salt / mililiters of solution] * 100
grams of salt = grams of salt from solution 1 + grams of salt from solution 2
grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g
grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x
mililiters of final solution = mililiters from solution 1 + mililiters from solution 2
mililiters of final solution = 80 mililiters + x mililiters
=> Final concentration, % = [0,10x + 20 g] / [x + 80 mililiters] * 100
