1. We can subtract the scores of the first and second rounds from the total score to obtain the score in the third round.
2. An equation including a variable to solve would be x + 30 + 25 = 100.
3. By solving the equation we obtain Amos scored 45 points in the third game.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
From the given information the score for her third round would be,
= (100 - 30 - 25).
= 100 - 55.
= 45.
Another way to solve this problem is assuming Amos scored 'x' in the third game.
Therefore, (30 + 25 + x) = 100.
55 + x = 100.
x = 100 - 55.
x = 45.

Which values of m and b will create a system of equations with no solution? Select two options. y = mx + b y = –2x + A
Answer:
(I can not see the options, so I will answer in a general way)
When we have a system of linear equations:
y = a*x + b
y = c*x + d
We have 3 possible options:
One solution: This happens when the lines intersect only one time, and the solution of the system is the point where the lines intersect.
No solutions: This happens when the lines do not intersect, is the case for parallel lines (lines with the same slope but different y-intercept)
Infinite solutions: This happens when the lines do intersect at infinite points, is the case for two equal lines (so both equations represent the same line)
Now we have the system:
y = m*x + b
y = -2*x + A
We want to find values of m and b, such that this system has no solutions.
Then we know that the lines must be parallel, again, the lines must have the same slope but different y-intercept.
Then we can use:
m = -2, b = A + 1
we will get:
y = -2*x + (A + 1)
y = -2*x + A
This system has no solutions.
Other pair can be:
m = -2, b = A + 3
we will get
y = -2*x + (A + 3)
y = -2*x + A
This system has no solutions.
m over 4=8 the answer is 32 what are the steps to this equation?
Explanation:
4x+8=32
Isolate for x. Start by subtracting 8 from both sides of the equation.
4x+8−8=32−8
4x=24
Divide both sides of the equation by 4.
4x4=244

0+0+0+5+6=7+10 = 28
28 divided by 7 is 4
To find mean you need to add up all the numbers then divided them by the total number of numbers there are. 0+0+0+5+6=7+10 has 7 numbers so I divided 28 by 7.

y = 2x - 8
x-y=3
What is X and Y
Answer:
x = 5
y = 2
Step-by-step explanation:
In this question, you will have to use one of the equations to find the value of x in terms of y and substitute it in the other equation or vice versa.
y = 2x - 8
x - y = 3
Use the second equation to find the value of x in terms of y.
x - y = 3
x = y + 3
Now that we found that, we can substitute it in the other equation.
y = 2 (y + 3) - 8
y = 2y + 6 -8
y = 2y -2
y + 2 = 2y
y = 2
Now that we got y we can substitute the value in any of the equations to find x.
x - 2 = 3
x = 5
