420-60=360 (time taken for lunch)

15mins=one ride

360÷15=24 rides

The system shown has the unique solution (2, y, z). Solve the system and select the values that complete the solution. y = 0 y =
madreJ [45]
So we are given a system:
3x-2y+3z=0\\
-3x - 5y - 5z= -21
Substitute x = 2 we get the system:
-2y+3z=-6\\
- 5y - 5z= -15
Multiply the first equation by -5 and the second by 2 we get the system:
10y-15z=30\\
- 10y - 10z= -30
Adding the two equations we get :
-25z=0\text{ then}z=0.
We find the value of y by using any of the other equations like this:
-2y=-6\\y=3.
Final solution:
z=0,y=3

Choose the correct simplification of (4x3 + 3x2 − 6x) − (10x3 + 3x2).
Ray Of Light [21]
Answer:
-6x (x + 1)(x - 1)

Explanation:
Before we begin, remember the following:
(-ve) * (-ve) = +ve
(-ve) * (+ve) = -ve
(+ve) * (+ve) = +ve
(+ve) * (-ve) = -ve
a² - b² = (a + b)(a - b)

Now, for the given:
(4x³ + 3x² - 6x) - (10x³ + 3x²)
First, we eill remove the brackets based on the rules mentioned above. This will give us:
4x³ + 3x² - 6x - 10x³ - 3x²
Now, we will combine like terms as follows:
(4-10)x³ + (3-3)x² - 6x
-6x³ - 6x
Taking -6x as a common factor:
-6x (x² - 1)
Factoring the bracket as difference between two squares will give us the final simplest form:
-6x (x + 1)(x - 1)

Hope this helps :)

Express each product in the simplest form. A. wx/6 B. wx/3 C. 2/3/wx D. wx
____ [38]

Answer:

A) \frac{wx}{6}

Step-by-step explanation:

\frac{3wx}{6x}\cdot \frac{3wx}{9w}

Multiply:

\frac{3wx\cdot \:3wx}{6x\cdot \:9w}

Cancel off the common factor "w":

\frac{3x\cdot \:3wx}{6x\cdot \:9}

Cancel off the common factor "x":

\frac{3\cdot \:3wx}{6\cdot \:9}

\frac{9wx}{54}

Cancel off the common factor "9":

\frac{wx}{6}
