Answer:
12n-17
Step-by-step explanation:
add like terms: 9n+3n and -16-1
Answer:
x > -5
Step-by-step explanation:
7b - 2b + 3 - 1 = 0
(7b - 2b) = 5b
3 - 1 = 2
Thus:
5b + 2 = 0
5b = -2
b = -2/5 = -0.4
1 Pint= 2 Cups= 16 ounces
1 Quart= 2 pints= 4 cups= 32 ounces
20x = 2*100
x = 10 ml (amt of 30% solution needed)
100-x = 90 ml (amt of 10% solution needed)
Very hard but I hope it helps
