Answer: x=−3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15x+9=3(2x−6)

15x+9=(3)(2x)+(3)(−6)(Distribute)

15x+9=6x+−18

15x+9=6x−18

Step 2: Subtract 6x from both sides.

15x+9−6x=6x−18−6x

9x+9=−18

Step 3: Subtract 9 from both sides.

9x+9−9=−18−9

9x=−27

Step 4: Divide both sides by 9.

9x/9 = -27/9

x=−3

Answer:

x= -3

Step-by-step explanation:

First let's work on the right side and use distributive property

15x+9= 3(2x-6)

15x+9= 6x-18

    -9         -9

15x= 6x-27

-6x  -6x

9x= -27

9x/9= -27/9

x= -3

Hope this helps!

Use the trend line to predict what the value of variable N will be when variable M equals 50.
ahrayia [7]

Answer:

N = 10

Step-by-step explanation:

Normally the coordinate system goes:

x axis (horizontal)

y axis (vertical)

Here, we have:

Horizontal axis as "M", and

Vertical axis as "N"

We want to know what N will be when M equals 50.

So, we look at the x-axis and go to M equals 50.

Then we move up until the "trend line". The intersection.

If we move directly left to vertical axis (N variable), we see that it is at the point:

N = 10

So,

When M = 50, N = 10

The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at
Ahat [919]
Distance = r x t ===> t=d/r

Distance (after 2 hours driving @30mil/hr) = 2 x 30 = 60 Mil

To drive same distance (60)  with r = 50, the time needed is 60/50 =1.2 hrs
