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)
Answer:
860
Step-by-step explanation:
Eight hundred and sixty.
Answer: 900
Step-by-step explanation:
Answer:
1. Angle Relationship: Alternate Exterior Angles
2. Angle Relationship: Same side Interior angles
3. Angle Relationship: Corresponding angles
Step-by-step explanation:
Alternate Exterior Angles are angles that are outside of the parallel lines and are opposite of each other.
Same side Interior angles are angles that are inside the parallel lines and are on the same side of a transversal.
Corresponding angles are angles that are in the same matching corners.
Hope this helps! :)
