Problem
8 over 3
g over 3
Cross multiply
8 × 3 = 24
g × 3 = 3g
__________
24 × 3g
--- ----
3 3
(Cross out "3g" and "3" on the right )
Then "divide" 24 and 3. It should leave you with 8
Your answer: g= 8
-15m -30 = -12m +6
3m = 36
m= 36/3 =12
The second option is your answer.
I can tell because any number to the power of 0 is equal to 1. So 2⁰ = 1.
The only one with a first term of 1 is the second option.
Sorry if you can’t read my handwriting but there you go. I did it in pen too so sorry.
