A, b and c stand for three different numbers
creativ13 [48]

To find the mean, you add up the numbers and divide by
how many numbers there are.

So if the mean of   'A' and 'B' is 40, then   A + B = 80 .
And if the mean of 'B' and 'C' is 35 then    B + C = 70.
==========================================
You said that     (A + B) + C = 100 .
 
From something else that you said, I noticed that      A + B = 80 .

So I can write        (80)    + C  =  100

Subtract 80 from each side:  C = 20
==========================================
I also noticed, from what you said, that    B + C = 70 .

So I can write                  B + 20 = 70

Subtract 20 from each side:    B  =  50
==========================================
Now I know that  C = 20  and  B = 50.

Finally, you said that           A + B + C = 100 ,

So I can write                   A + 50 + 20 = 100

Combine like terms on the left:  A + 70 = 100

Subtract  70  from each side:      A      =  30
==========================================

           <em>  A = 30</em>
<em>             B = 50</em>
<em>             C = 20</em>

Could someone please assist me in getting the answer? I will give branliest.
Mrac [35]

Answer:

9

Step-by-step explanation:

You know that the the center line is equal to half the sum of the legs, because it is the midline. You add the legs together (7x+13) and (5x+7), and you get 12x+20. Divide that by 2 and you get 6x + 10. The midline is 8x-8, so you set up an equation, and get 6x+10 = 8x-8. That simplifies to 18=2x. Divide both sides by 2 and you get x = 9

Which system of equations could be graphed to solve the equation below?
vodomira [7]

Answer:

B

Step-by-step explanation:

<u><em>I think this is your full question and hope it is correct. </em></u>

<em>Which system of equations could be graphed to solve the equation below? </em>

<em>log(2x+1)=3x-2 </em>

<em>A. y1=3x, y2=2x </em>

<em>B. y1=log(2x+1), y2=3x-2 </em>

<em>C. y1=log2x+1, y2=3x-2 </em>

<em>D. y1=log(2x+1+2), y2=3x</em>

My answer:

We know that: log(2x+1)=3x-2  and they are a equation of log and linear so we need to make system of equation.

The left side is: y_{1} => y_{1} = log( 2x+1)

The right side is : y_{2}  = 3x -2

The system of equations are:

\left \{ {{y_{1} =log(3x+1)} \atop {y_{2} =3x -2}} \right.

Now we have two new function with x and y.
