-4(6x+3)= -12(x+ 10)

Lilit [14]

Answer:

Step-by-step explanation:

-4(6x+3)= -12(x+10)

Let's do the first part:

-4(6x+3)

**distribute**

-4 x 6x = -24x; -4 x 3 = -12 ->>> -24x - 12

Let's do the second part:

-12(x+10)

**distribute**

-12 x x = -12x; -12 x 10 = -120 ->>> -12x -120

-24x -12 = -12x - 120

**Move variable to the left-hand side and change its sign**

-24x +12x -12 = -120

-12x - 12 = -120

-12x = 108

x = 108/-12

x=9

The math teacher gives each student a map of the amusement park that use a coordinate plane the meeting locates is at(0,0) on th

GrogVix [38]

Given:

Starting point = (0,0)

First ride = (0,4)

Second ride = (3,0)

In map, each unit = 100 ft

To find:

The actual distance between first and second ride.

Solution:

Distance formula: Distance between two points is

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Using the distance formula, we get the distance between first ride and second ride in the map is

$d=\sqrt{(3-0)^2+(0-4)^2}$

$d=\sqrt{9+16}$

$d=\sqrt{25}$

$d=5$

So, the distance between first ride and second ride in the map is 5 units.

We have,

1 units = 100 ft

5 units = 500 ft

The actual distance between first and second ride is 500 ft.

Therefore, the correct option is C.
