Hey buddy I am here to help!
Red = 8
blue = 6
greem = 4
total = 18
probability of blue marble = 6/18 = 1/3
Part A: X=(35-(100*0.10))/5 35= 5X+(100*0.10)
Where X is the number of dogs he walked.
Part B: To solve the equation just simplify it by using inverse operations. It should give you 5 dogs walked. The algebraic property justifying this is inverse operations.
Part C: Emerson walked 5 dogs last week.
Answer:
The answer is True because CPCTC stands for Corresponding Parts of Congruent Triangles are Congruent.
Your answer is 89 since 4*10=40)+5*5=25)+2*12=24, add all the results up and get 89.

now, you're asked to use it when ln(1.38), which is just another way of saying x = 1.38
so set x = 1.38 and see what "y" is
