For this case we have the following relationship:
27:9
To find two equivalent relationships, what we must do is divide both numbers by a number that is multiple of both.
We then have to divide by three:
9:3
Then, dividing again between three we have:
3:1
Answer:
two ratios that are equivalent to 27:9 are:
Ratio 1:
9:3
Ratio 2:
3:1
Answer:
The change in the standard of living, measured by growth in real GDP per person, is 0.1356%
Step-by-step explanation:
Given,
In the current year,
Population = 31.5 million,
Real GDP = $814 million,
So, the real GDP per person = 
≈ 25.841
In the previous year,
Population = 31 million,
Real GDP = $800 million,
So, the real GDP per person = 
≈ 25.806
Hence, change percentage = 
≈ 0.1356 %
It's
because this choice made the most since.

Answer:
(x, y) = (3, 12)
Step-by-step explanation:
Using the given variable definitions, we can write the equations ...
y = x + 9
2(x +y) = 30
__
Solving the second equation for y, we have ...
y = 15 -x
Substituting this into the first equation gives ...
15 -x = x +9
6 = 2x . . . . . . . . . add x-9
3 = x . . . . . . . . . . divide by 2
y = 3+9 = 12 . . . . substitute into the first equation
The numbers are (x, y) = (3, 12).
