Answer:

22.1 grams

Step-by-step explanation:

At the end of each minute, (1 -17.1%) = 82.9% of the element remains. At the end of 19 minutes, the quantity has been multiplied by that value 19 times, so the remaining amount is ...

The angles are complementary.

This means they add to 90 degrees.

(2x + 1) + (x + 5) = 90.

3x + 6 = 90. (Combine like terms)

3x = 84. (Subtract 6 from each side)

x = 28. (Divide 3 from each side)

x = 28

D is correct
