Answer:

Ms. Day bought 5 blankets and 4 pillows.

Step-by-step explanation:

Let x denotes number of blankets and y denotes number of pillows.

Blankets cost her $16 while pillows cost her $10 and Ms. Day spent a total of $120.

16x+10y=120

Divide this equation by 2.

8x+5y=60\,\,...(i)

Ms. Day bought 9 items.

x+y=9

Multiply this equation by 5.

5x+5y=45\,\,...(ii)

Subtract (ii) from (i)

3x=15\\x=5

Put x=5 in x+y=9

5+y=9\\y=9-5\\y=4

Therefore,

Ms. Day bought 5 blankets and 4 pillows.

Step-by-step explanation:

A

B

1 ounces equal 29,57 milliliters

if we have 2 1/2 ounces then we multiply 2,5 *29,57

the answer is 73,9 milliliters
