The answer is 49 because since she multiplied 5 by 7 you have to do the same to yellow marbles so 7×7 = 49
Answer:
- 0.5
Step-by-step explanation:
you first change the fractions numbers in to decimal form

hence; 0.4 + (-0.875)
= - 0.475
in to its simplest form = - 0.5
the answer is - 0.5

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
