Answer:

1.) 9

2.) 20

Step-by-step explanation:

1.) 39 is incorrect because they didn't follow the PEMDAS rule.

They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.

The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.

2.) 12 is incorrect because they didn't use PEMDAS.

They added 8 to 16 which is 24, and then divided 24 by 2.

The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.

The dose of a strong cough medicine might be which of the following? 2mL, 200mL, 2L

Margarita [4]

To find the answer,we can picture how much the above value is by objects in real life.

2mL = about two drops of water

200mL = about a carton of milk/ a box of ornage juice

2L = 2000 × 10 mL = 20000 mL = The bottle of drinks that are in family/party size.

As we only take in small dosages of medicine, the best option would be 2mL.

Hope it helps!
