Answer:
Sue is correct
Step-by-step explanation:
because of the simple fact that the numbers are increasing and not decreasing so why would they do 8n-6
9 x 5 - 3 x 1
45 - 3 = 42
answer: 42
X=+6 and -6 due to factoring fine the equation. It would be distributed from (x-6)(x+6) and you would equal that to zero and get the answer 6 and -6
Answer:
There are no solutions
Step-by-step explanation:
2(x+1)=2x+5
Distribute the values on the left:
2x+2=2x+5
subtract 2x from each side
2x(-2x)+2=2x(-2x)+5
2=5
These value are not equal so there are no solutions
Answer:
Movie: $4.25
Video Game: $5.25
Step-by-step explanation:
For this problem, we can use system of equations to solve for the rental costs of the movies and video games. Let's use x for movies and y for video games.
Equation 1
5x+3y=37
Equation 2
2x+6y=40
To start, we can use elimination to solve for x and y. Let's cancel out y. To do so, we have to multiply the first equation by 2 to get the y equal.
10x+6y=74
Now that the y are equal, we can subtract both equations.
8x=34
x=4.25
The movie rental cost is $4.25.
Now that we know x, we can plug in to find y.
2(4.25)+6y=40
8.5+6y=40
6y=31.5
y=5.25
The rental cost for video games is $5.25.
