Answer:
x=-2
Step-by-step explanation:
same on both sides
(84x - 69y) - (65x + 34y)
Remove the parenthesis and combine the like terms:
84x - 65x = 19x
-69y - 34y = -103y
Combine for final answer:
19x -103y
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
Answer:
4(x - 2)^2 + 3x – 2 + 1 = 0
Step-by-step explanation:
The equation that has a highest x-power (degree) of 2 is quadratic.
The degrees of the answer choices are ...
So, only the first answer choice is a quadratic.
