Step-by-step explanation:
We can make 2 equations as follows:
2x = y + 16 and x + 2y = 18
x + 2y = 18 is the same as x = 18 - 2y. Hence, 2(18 - 2y) = 2x = y + 16.
2(18 - 2y) = y + 16
36 - 4y = y + 16
5y = 20
y = 4.
The ratio is 4:9 to get from 4 to 36, you need to multiply 4 by 9. Now you need to do the same to 9. multiply 9x9 to get 81. The new ratio is 36:81, with 3 point tries being 81.

Answer: A.This statement makes sense because Emily makes more money than Emma, so she has a greater cash flow at the end of the month.
Step-by-step explanation:
Emily has more monthly income and even if the duo spend exactly the same figure on everything they participate in, Emma will always come off short (negative monthly cash flow) because she does not earn as much as Emily does but spends equally.
