Answer:

Step-by-step explanation:

12/3 = 4

4 - 2 = 2

x = 2

using the order of operations, you would first have to do y + 3

y = 12

12 + 3 = 15

the equation simplified is 3 x 2 + 5 x 15

3 x 2 = 6

5 x 15 = 75

75 + 6 = 81

You've just purchased 12 lb of celery. You take it back to your kitchen and proceed to trim and cut it into pieces, ending up wi

Alecsey [184]

We should know that ⇒ 1 lb = 16 oz

The amount of purchased celery = 12 lb = 12 * 16 = 192 oz
Trim and cut it into pieces, ending up with 5.5 oz of trim.

The yield will be = 192/5.5 = 34.91

Taking the smallest integer number.

So, the yield = 34

which will be equal = 34*5.5 = 187 oz


So, the yield percentage = $\frac{187}{192} *100 = 97.4 \%$
