Answer:
d = sqrt(x2-x1)^2 + (y2-y1)^2
d = sqrt(4-3)^2 + (-3)^2
d=sqrt(1+9)
d=sqrt10
d=3.2
Let me know if this helps!
A) total cost = 3b+(9*5)
B)

Answer:
D. 0.925x + 0.88y = 0.91(x + y)
Step-by-step explanation:
The important point to remember is that the total mass of pure silver is the same on each side of the equation.
0.925x = mass of pure silver in first alloy
0.88 y = mass of pure silver in second alloy
The final alloy has a mass of (x + y) g and is 91 % pure silver, so
0.925x + 0.88y = 0.91(x + y)
