B. 20 more points

**Step-by-step explanation:**

A. 100 is half of 200, and 50% is half of 100%.

B. 60% is a D, but it is still passing. Sine 200=100 x 2, we need to multiply 60 x 2. 60 x 2=120

4. Find a value of x that is a solution to 5(x - 3) = x + 13. Describe how you found the solution

### Answers

**Answer:**

x=7

**Step-by-step explanation:**

5(x - 3) = x + 13

Distribute the 5

5x-15 = x+13

Subtract x from each side

5x-15-x = x+13-x

4x-15 =13

Add 15 to each side

4x-15+15 = 13+15

4x= 28

Divide each side by 4

4x/4 = 28/4

x = 7

**Answer:**

x = 7

**Step-by-step explanation:**

First

5(x - 3) = 5x - 15 by distributing the 5 on each variable and number in the parenthesis.

Then

5x - 15 = x + 13 which you add 15 (or 5x - 15 + 15 = x + 13 +15) on both sides to have the numbers on one side because it must be the opposite to cancel out the 15 on the original/previous side.

Afterwards

5x = x + 28 now we must get the x to the other side and using the same logic as before you move the x to the other side by subtracting it (or 5x - x = x + 28 - x) to the other side equaling 4x = 28.

Finally

4x = 28 you need to divide each side by 4 to cancel out the 4 on the x since we must find out what x is (or 4x/4 = 28/4), and you should get x = 7.

¿Qué fuerza media se requiere para que un objeto de 2 Kg aumente su velocidad de 5 m/s a 12 m/s en una distancia de 8 m?

### Answers

**Answer:**

14.87

**Step-by-step explanation:**

Para conocer cual es la fuerza que necesita el cuerpo para aumentar su velocidad de 5 m/s a 12 m/s en 8 m

Necesitamos conocer la aceleración y para conocer la aceleración debemos saber cuanto tiempo tarda en recorrer los 8m

Vf = Vo +a(t)

12 = 5 +a(t) -------> Vamos a despejar el tiempo.

t = 7/a

X= Vo(t) +1/2a(t²)

X= 5(7/a)+1/2a( 7/a )²

8 = 35/a+49/2a

a = 7.43 m/s²

Ahora que conocemos la aceleración podemos calcular la fuerza como:

F = m*a

F = 7.43 * 2 kg.

F = 14.87

### Answers

**Answer:**

Aidan can expect to save about $17.63 each week.

**Step-by-step explanation:**

We have an equation: y = 17.63x + 27.52. This equation is in *slope-intercept form*. In slope-intercept form, the value before the x (in this case, 17.63) is the slope, and the value added to the slope (in this case, 27.52) is the y-intercept.

Right now, though, we only need to focus on the slope. The slope represents a change in y over a change in x. Our y-values represent *total amount saved*, and our x-values represent *number of weeks*. Y over x... so, total amount saved over a certain number of weeks.

The first answer seems to match this the best. Remember that the slope represents how much is saved per week, and our slope is 17.63. So, the first answer (**Aidan can expect to save about $17.63 each week**) is correct. If you have any more questions or that was confusing at all, let me know! :)

**Answer:**

Its C (Third Multiple Choice Answer)

**Step-by-step explanation:**

The reason being that x + 1 / 2 (6x - 4) = 6 is the way it is instead of the first step being x + 6x / 2 - 4 / 2 = 6 is because it is using legal manipulation by multiplying the 1 / 2 out.

Math:

First

2 * (x + 1 / 2 (6x - 4) = 6 * 2 [In this case the x gets multiplied by 2 and multiplies 2 to the other side as well. The reason why it isn't a Distributive Property in the first place is because we are using multiplication only and the equation is not 1 / 2 (6x - 4).

Then

2x + 6x - 4 = 12 will then equal to 8x - 4 = 12 which is adding like terms

Thirdly

(+ 4) + 8x - 4 = 12 (+ 4) [The parenthesis is to identify that the 4 is positive]

will then turn into 8x = 16

Finally

By dividing 8 on both sides of the previous equation

8x / 8 = 16 / 8 equaling x = 2.

### Answers

**The value in cents of ****a ****nickels = 5***a*

[] A nickle is worth 5 cents, so 5*a* is the value of *a* nickles

**The value in cents of ****a**** dimes = 10***a*

[] The value of a dime is 10 cents, so 10*a* is equal to *a* dimes

**The value in cents of**** a**** quarters = 25***a*

[] A quarter is worth 25 cents, so 25*a* is the value of *a* quarters

**The value in cents of ****a**** dimes and one quarter = 10***a ***+ 25**

[] Up above we figured out the expression for *a *dimes, so we need to add 25 to it for one quarter

**The value in cents of 13 dimes = 130**

[] A dime is worth 10 seconds, so 13 * 10 = 130
