1. What would you measure your mass with?

a. mg b. g c. kg

2. What is a simpler way to write 12d+7d+5-3d+2d? (add together all the numbers with hdh keep the hdh after the total)

My Guesses:

1. kg

2. I have two answers:

I am pretty sure it is: 24d-5

OR

my other answer (I do not think this one is write) is: 18d+5

Please help me! Thank you so much.
