Step-by-step explanation:
We know that Judy picked up 5 times as many apples as Marcus. We also know that Marcus has <em>a</em> apples. In order to find out how many Judy has, we simply multiple how many apples Marcus has by 5. When we do that, we get
5 x <em>a </em>= 5<em>a</em>
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
