Write a system of equations AND solve using elimination

Mathematics
1 answer:
Inessa [10]3 years ago

Answer:

98 small cups, and 57 large cups!

Step-by-step explanation:

x+y = 155

1.25x+ 2.50y = 265

1.25x + 2.50 ( 155 - x) = 265

1.25x + 387.5 - 2.50x = 265

-1.25x = 265-387.5

-1.25x = -122.5

x=98; y = 57

2/5 + k/4 = 9/10 (solve with work)
Alla [95]

The LCD of 2/5 + k/4 = 9/10 is 20. Applying this LCD, we get:


8 + 5k = 18. Subtracting 8 from both sides: 5k = 10. Then k = 10/5, or k = 2.
