Answer:
3.95m + 8.95b = 47.65
Why?
It cannot be the first or second equation since the total amount was $47.65, not $60.55 or $47.95.
It’s either the third or fourth equation. You can tell it’s the third one since in the question it states “Let m represent the number of magazines and b represent the number of books.” The fourth equation gets it reversed by saying each magazine costs $8.95 and each book costs $3.95, when in reality it’s the other way around.
Therefore, the third equation most accurately depicts this situation.

Saige's spaceship traveled 588 588588 kilometers ( km ) (km)left parenthesis, start text, k, m, end text, right parenthesis in 6

pshichka [43]

Answer:

The first ship has the same speed as Saige's ship while the second and third do not have the same speed.

Step-by-step explanation:

d = Distance traveled by Saige's spaceship = 588 km

t = Time taken = 60 seconds

Speed is given by

$s=\dfrac{d}{t}\\\Rightarrow s=\dfrac{588}{60}\\\Rightarrow s=9.8\ \text{km/s}$

The other ships

$s=\dfrac{441}{45}=9.8\ \text{km/s}$

$s=\dfrac{215}{25}=8.6\ \text{km/s}$

$s=\dfrac{649}{110}=5.9\ \text{km/s}$

So, the first ship has the same speed as Saige's ship while the second and third do not have the same speed.

Multiply and solve for x: x(x + 12) – 8x = 14 + x(x – 4)

erik [133]

Using the distribution method:

x^2 + 12x - 8x = 14 + x^2 - 4x

x^2 + 4x = x^2 - 4x + 14

Now, I'm isolating x by moving all the x's onto one side of the equation:

x^2 - x^2 + 4x + 4x = 14

Combine like terms (x^2 cancels out):

8x = 14

x = 14/8

Simplified: x = 7/4
