Hello there! I can help you! In order to answer those questions, we need to plug in the values, based off of the variable.
g. Okay. We are solving b - 10. b = -8. When you subtract something from a negative number, the number is even lower. Let's add the numbers first and then put in the negative symbol. 8 + 10 is 18. Put the negative sign and you get -18. The difference is -18.
h. Now, we solve a - b. a = 5 and b = -8. Because we are subtracting a negative number from a positive, we have to add both numbers, which means the number gets bigger. Ignore the negative sign and add. 5 + 8 is 13. There. The sum is 13.
i. The problem is c - a. c = -9 and a = 5. So as explained on problem G, for this problem, ignore the negative symbol and add. 9 + 5 is 14. Plug in the negative sign to get -14. There. The difference is -14.

ASA
Step-by-step explanation:
Answer:
x = 7
y = 4
Step-by-step explanation:
The sum of two numbers equaling 11 can be written as
x + y = 3
The difference of the two numbers equaling 3 can be written as
x - y = 3
Where x and y represent the unknown numbers
So now we have a system of equations
We can solve for y in the 1st equation by subtracting x on both sides
x + y = 11
y = 11 - x
We can plug the expression for y into the 2nd equation and solve for x
x - (11 - x) = 3
x - 11 + x = 3
2x - 11 = 3
2x = 14
x = 7
Now we can plug 7 for x into any of the equations and solve for y
1st equation:
7 + y = 11
y = 4
2nd equation:
7 - y = 3
-y = -4
y = 4
So, x = 7 and y = 4
Hope this helped!
Answer:
The game's expected value is of -$1.5.
Step-by-step explanation:
Expected value:
Probability of each outcome multiplied by the outcome.
One out of 6 sides is 2:
1/6 probability of the player earning 45 - 9 = $36.
5/6 probability of the player losing $9. So
The game's expected value is of -$1.5.
