If 3r = 18, what is the value of 6r + 3

Mathematics
2 answers:
Free_Kalibri [48]3 years ago

Answer:

39

Step-by-step explanation:

In order to solve this you have to fond r.

In 3r=18 you divide the 3 from both sides to isolate the variable.

18÷3=6 so you are left with r=6

So r is 6.

Plug that into 6r+3

6(6)+3

6×6=36

36+3=39

Answer:

39

Step-by-step explanation:

     <em>3r = 18 </em><em>(given in the question)</em>

<em>          r = 18 / 3</em>

<em>           r = 6</em>

<em>substituting r = 6 in the equation we get:</em>

<em>        </em><em>  = 6r + 3</em>

<em>         = 6 (6) + 3   </em><em>(by multiplying 6 (6) u will get 36)</em><em> </em>

<em>         = 36 + 3 = </em><em><u>39</u></em>

                          Hope it helps

                                        All the best!

Is y=2x-8 and 2x-y=8 a dependent independent or inconsistent
kolbaska11 [484]
Note that 2x-y=8 can be solved for y:  y=2x-8.  This is identical to the first equation.  The graph of one is exactly the same as the graph of the other.  Thus, the two equations are dependent.

James decides to walk from school to the park to play ball. The park is only 0.5 mile from the school. He leaves school at 3:15
miskamm [114]

Answer: C

Step-by-step explanation: We see that it took James 10 minutes to go 0.5 miles, so to get how many miles an hour James is traveling, we need to get the miles to 1. To do this, multiply by 2, and this will give you that it took James 20 minutes to go 1 mile. This is option C.

What is the solution to the system of equations? -2x + y = -5 3x – 2y = 12 A) (3, 1) B) (6, 3) C) (-2, -9) D) (-2, -1)
max2010maxim [7]

Answer:

The correct answer is D) (-2, -1)

Step-by-step explanation:

In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.

-4x + 2y = -10

3x - 2y = 12

---------------------

-x = 2

x = -2

Now that we have the value for x, we can find y by plugging the x value into either equation.

-2x + y = -5

-2(2) + y = -5

-4 + y = -5

y = -1
