Rita had the higher score by 12 points
To create this pattern, you can start with the number zero and apply this math. 0 x 2 +1 = 1. The next number would be found by taking 1 x 2 + 1=3. After that 3 x 2 + 1 = 7. The next number in the pattern would be found by taking 7 x 2 +1. Essentially, you are just taking the answer you just got and doubling it and then adding 1. Here is the pattern that would be created beginning with 0. 0, 1, 3, 7, 15, 31, 63, etc...
Let x and y be the two numbers
Saying "The sum of two numbers is 27" means x+y = 27. The term "sum" is the result of adding. So the first equation is x+y = 27
The second equation is y = x+3 where we assume that y is the larger number of the pair.
So your system of equations will be
x+y = 27
y = x+3
Use substitution to solve this system.
x+y = 27
x+( y ) = 27
x + (x+3) = 27 ... notice how y has been replaced with x+3 (since y = x+3)
x+x+3 = 27
Solve for x and then use this to find y. I'll let you finish up.

Answer:
Step-by-step explanation:
Given linear inequality:
Solving for
Subtracting both sides by 5.
Dividing both sides by 2.
∴
The graph of the inequality is shown below.
The line is represented by dotted line because the inequality sign is only greater than which means 22.5 is not included in the solution.
