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.

a. Yes, kg is more convenient, but you really could use any of those units.

b. 18d+5 is the correct answer

12d, 7d, 2d and -3d add up to +18d.

The +5 doesn't get added to anything else.
