Answer:
Here are just three examples I came up with:
-9(2 + 3)
or
-3(6 + 9)
or
-(18 + 27)
Step-by-step explanation:
- To come up with these expressions, I found common factors between the numbers -18 and -27.
- Then, I factored the numbers with the common factor (the common number is the number outside of the parentheses.)
- When you distribute any of the expressions above, you will find they they can be simplified to -18 - 27, which is the same as -18 + (-27).
Answer:
c) 160,000
Step-by-step explanation:
Since we know that the population of both city x and city y are equal in 2015, we can use the population growth of population of city x to find the population in 2015:
120,000 x 1.2 = 144,000.
Now, since we know that City Y's population decreased 10% from 2010 to 2015, we can divide the 2015 population of city Y (which is the same as city x - 144,00) by 1 - decrease rate to find city y's population in 2010:
1 - .1 = .9
144,000 / .9 = 160,000
I hope this helps!

Answer:
25 degrees
Step-by-step explanation:
Angles 4 and 6 are supplementary angles since they as same side interior angles for parallel lines cut by a transversal. This means angle 4 + angle 6 = 180. If angle 6 is 155 then angle 4 must be 25 degrees
The answer is D. 3/8 in 1/2 hour, multiply by 2, since 1/2 times 2 is 1, meaning 1 hour. You will get 6/8, by simplifying that, you get 3/4.
Answer:
The son is 7, the father is 49.
Step-by-step explanation:
This was a guess-and-check process. I knew this answer was correct because 7*7=49, and 49+7=56.
