If we use the last equation:
2 x = 18
x = 18 : 2
x = 9
Then we will put it in another equation:
x - 2 y = 3
9 - 2 y = 3
- 2 y = 3 - 9
- 2 y = -6
y = -9 : ( -3 )
y = 3.
The solution is : D ) ( 9, 3 )

mrs.saledo wants to buy 1 1/2 quarts of whipping cream if whipping cream is sold in only 1 pint containers , how many containers

hram777 [196]

Answer:

She needs to buy 3 such containers.

Step-by-step explanation:

Mrs. Saledo wants to buy $1\frac{1}{2}$ quarts of whipping cream.

Now, $1\frac{1}{2}$ quarts = $\frac{3}{2}$ quarts = $\frac{3}{2} \times 2 = 3$ pints.

Since we know that 1 US liquid quart = 1 US liquid pints.

If the whipping cream is sold in only 1 - pint containers, then she needs to buy 3 such containers. ( Answer )
