Answer:

5x-9y-42=5(x+6)-9(y+8)

Step-by-step explanation:

given 5x-9y-42=5x-9y-72+30

                        =5x+30-9y-72

                        =5(x+6)-9(y+8)

                      hence 5x-9y-42=5(x+6)-9(y+8)

kkurt [141]
Hello

Answer: The ratio of the first 6 months to the last 6 months is 0.765.
First, we need to determine the amount of money they had in each 6 month period.
In the first 6 months they had: 6 x 76500 = 459000
In the second 6 months they had: 6 x 100000 = 600000
Divide the 2 values to find the ratio:  459000 / 600000 = 0.765

A bird population is decreasing by 3 percent each year. Find the bird population after 6 years.
QveST [7]

Hello!

If it is decreasing by 3% each year, 18% of its population will have decreased after 6 years. As we do not have an original number, we will just say that the population is 18% less than the original.

If you want to find the exact number, multiply the original population by 0.18. Subtract the number from the original population.

I hope this helps!

In congruent figures, corresponding angles have equal measures. true or false?
algol [13]
This is true

Think of two houses. If we say "the houses are identical" then the corresponding pieces must be the same (eg: the doors must be the same type out of the same material). In this analogy, the houses are the triangles, which are the overall structures. The doors are the angles since they are pieces of the overall structures. This is what CPCTC is saying

CPCTC = Corresponding Parts of Congruent Triangles are Congruent

Once again, the final answer is true.
