Answer:

7m^3-11m^2+5m+17

Step-by-step explanation:

it'll be really hard to show work so just trust me on this one-

hope it helps <3

For m^3 : Because you are subtracting a negative from a negative, that means you are adding, therefore the first part should be 7m^3

For m^2 : because you are subtracting a positive from a negative, that means you are subtracting, so it would be -11m^2

For m : because you are subtracting a negative from zero, it would turn into a positive, making it just 5

For the constant : subtracting positive 8 from negative 9 makes it a positive from the double negative. Therefore you would add 8+9, giving you 17

FINAL ANSWER : B. (7m^3)-(11m^2)+5m+17

The model below represents an equation. Write the equation that is modeled then find what value of x makes the equation true. HELP ASAP PLZ PLZ PLZ PLZ

Answers

Answer:

x = 5

Step-by-step explanation:

6x - 5 = 4x + 5

The only thing that makes x true is 5. (This might not help if I read the question wrong.)

Answer:

6x-5=4x+5

x=5

Step-by-step explanation:

6x-5=4x+5

Subtract 6x from both sides

-5=-2x+5

Subtract 5 from both sides

-10=-2x

Divide by -2 on both sides

x=5

Explain how to solve the equation and how to check the solution.
40 = 8y


there the answers-
Use the inverse operation to isolate the variable. Undo multiplication by dividing by 8 on both sides of the equation. Simplify by completing the divisions, 40 ÷ 8 = 5, and 8 ÷ 8 = 1. The solution is y = 5. Check the solution by substituting 5 for y in the original equation, and then simplify. 8 × 5 = 40 and 40 = 40 is a true statement, so 5 is the solution.

I have a triangle: Angle A = 3x +28; Angle B = 5x +52; Angle C = 2x - 10: Solve for X

Answers

I have no clue if I even did this right but here’s my work. I don’t wanna get it wrong for you!
Answer: x=11


Explanation: The anglers in a triangle must all add to 180.

Therefore, we can use the equation 180=3x+28+5x+52+2x-10

Combing like terms gives us 180=10x+70

Solving for x gives us 11.

To check our work, we can plug in 11 for x.

3(11)+28+5(11)+52+2(11)-10=180.
