3y= 21

I think 3y would be 21 because in the equation, 5y+13=48, y= 7. So if we know that y is 7 that’ll mean we’ll use 7 to interpret y for 3y.

Answer:

8.83 x 10^-5 grams

Step-by-step explanation:

3.7 x 10^-6 grams of carbon power

0.000092 grams of ammonium carbonate

0.000092 = 9.2 x 10^-5

3.7 x 10^-6 = 0.37 x 10^-5

The difference:

(9.2 x 10^-5 ) - (0.37 x 10^-5)

= (9.2 - 0.37) x 10^-5

= 8.83 x 10^-5
