Y=2.5 and if u need me to explain i will be glad to
Answer:
This is the answer hope you have a nice day
Y = mx + b
7x + 8y = -12
Subtract 7x from both sides
8y = -7x - 12
Divide each side by 8
y = -7/8x - 12/8
Simplify
y = -7/8x - 3/2
So besides simplifying, if I’m doing this correctly, it should be correct.
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
