We just substitute in -12 for x in each one and see if it's true
2(-12)+6 = -24 + 6 = -18, not 30, NOPE
-0.25(-12) - 1 = 3-1 = 2, that worked, CHECK ME
-12 - 8 = -20, CHECK ME
-35(-12) +2 = 422, not -515, NOPE
3(-12+25)=3(13)=39, CHECK ME
Answer: 2 4/15 months
Step-by-step explanation:
From the question, we are informed that a wagon train traveled from Missouri to Wyoming in 1 2/3 months and from Wyoming to Utah in 3/5 month.
The number of months that it will take the wagon train to travel from Missouri to Utah will be:
= 1 2/3 + 3/5
The common lowest multiple is 15
= 1 10/15 + 9/15
= 1 19/15
= 1 + 1 4/15
= 2 4/15 months
It will take they train 2 4/15 months to travel from Missouri to Utah.
