4x+5x = 90
9x = 90
x = 10
10y + 10 + 5x = 180
10y + 10 +5(10) = 180
10y + 60 = 180
10y = 120
y = 12

Answer:
12 cups of water
Step-by-step explanation:
This question has to do with conversion
We are told that she buy 1 quart and 1/2 gallon of water.
Hence,
1 quart of water = 4 cups of water
1 gallon of water = 16 cups of water
1/2 gallon of water = x
Cross Multiple
x = 1/2 × 16 cups of water
x = 8 cups of water.
Therefore, the total cups of water that she bought = 4 cups of water + 8 cups of water = 12 cups of water
Answer:
80
Step-by-step explanation:
50 problems/x total = 62.5%
50/62.5=0.8 problem for each percent
0.8 * 100 percent = 80 problems
9 times 4 = 4 times (9) because it equals to itself.
9 time 4 is 36
4 times 9 is 36
