Answer:

\Huge\boxed{\mathsf{\Rightarrow X=-6}}}

Step-by-step explanation:

Isolate x on one side of the equation.

2(-2x-4)  ← (Expand by using with distributive property.)

<u><em>DISTRIBUTIVE PROPERTY</em></u>

⇒ A(B+C)=AB+AC

⇒ A(B-C)=AB-AC

A=2

B=(-2x)

C=4

2(-2x)-2*4

-2*2x-2*4

-2*2x-2*4 (Solve.)

-2*2-2*4=-4x-8

Rewrite the equation problem.

10-x=-4x-8

10-x-10=-4x-8-10 (Subtract 10 from both sides.)

Solve.

-x=-4x-18

-x+4x=-4x-18+4x (Then, add 4x from both sides.)

3x=-18 (Solve.)

3x/3=-18/3 (Divide by 3 from both sides.)

-18/3 (Solve & Simplify.)

-18/3=-6

X=-6

\Large\boxed{\mathsf{X=-6}}}

Therefore, the correct answer is x=-6.

A car is moving at 45mph. Once the care starts to break, its speed(s) is related to the number of seconds(t) it spends breaking
lana [24]

Step-by-step explanation:

When the car stops, the speed is zero.

When S = 0, -10t + 45 = 0, t = 4.5.

Hence it will take 4.5 seconds for the car to stop.

Answer:

1. y² - 3x - 18

2. 4x² - 33x + 35

3. 12x² - 11x + 2

Step-by-step explanation:

All we do with these questions are expanding the factored binomials. Use FOIL:

1. y² + 3y - 6y - 18

y² - 3y - 18

2. 4x² - 28x - 5x + 35

4x² - 33x + 35

3. 12x² - 3x - 8x + 2

12x² - 11x + 2

An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $13
krek1111 [17]

Answer:

The number of half-page advertisements is 4.

The number of Full-page advertisements is 11.

Step-by-step explanation:

According to the Question,

  • Given, An advertising company charges $60 per half-page advertisement and $100 per full-page advertisement. Michael has a budget of $1340 to purchase 15 advertisements.

Let, 'x' be the number of half-page advertisements and 'y' be the number of full-page advertisements.

  • Thus, 60x + 100y is the money charged, and given that he has a budget of $ 1340.

       60x + 100y = 1340

  • And, the number of advertisements is 15. So, the other equation is

       x + y = 15

Now, We have Two Equations,

60x + 100y = 1340 and x + y = 15

  • the solution of the system is Put x=(15-y) in Equation 60x + 100y = 1340

60 (15-y) + 100y = 1340

900 - 60y + 100y = 1340

40y = 1340 - 900

40y = 440

y = 440/40

y = 11 So, For x = 15 - y ⇒ 15-11 ⇒ x=4 .

  • Thus, the number of half-page advertisements is 4 and The number of Full-page advertisements is 11 .
