(3y - 8)             y
----------    =  ----------
  12                  5

cross multiply

5(3y - 8) = 12y.....distribute thru the parenthesis
15y - 40 = 12y ....subtract 15y from both sides
-40 = 12y - 15y....simplify
-40 = -3y ....divide both sides by -3
-40/-3 = y
13 1/3 (or 13.333) = y

Reptile [31]

<em>Greetings from Brasil...</em>

According to the question of the statement, we can conclude that

PQ = 2B

QR = 2B

PR = base = B

Perimeter = P = 105

P = PQ + QR + PR

105 = 2B + 2B + B

B = 21

<h2>PQ = 2B = 42</h2><h2>QR = 2B = 42</h2>

4(2m-5)=2(3m-4)-6m what is the value of M
Schach [20]

Answer:

\frac{3}{2}

Step-by-step explanation:

4(2x - 5) = 2(3x - 4) - 6x =   \\  8x - 20 = 6x - 8 - 6x = \\   8x = 20 - 6  \\  \frac{8x}{8}  =  \frac{20 - 8}{8}  \\  x =  \frac{3}{2}

hope its clear ♡

Which inequality is graphed on the coordinate plane?
ruslelena [56]

Answer:

A: y < -2x - 1

Step-by-step explanation:

First, to figure out which part of the graph to be looking at, you will look at the shaded region as the solution area.

So, the solution area is to the left of the line. Said line is a dotted line which means that the points on the line can not be a solution.

If the points on the line can not be a solution then it eliminates answer choices C and D because y can not equal the other side of the inequality.

Now, we will bring the shaded region back into focus to find out if y is greater than or less than the other side. The shaded area is "below" the line so it is less than -2x - 1.

To ensure this is correct, plug two points into the inequality we just chose, one from the shaded region and one not, just to make sure the answer is correct.

I picked (-3,4) to test. So plug them into the inequality to get:

4 < -2 (-3) - 1

So 4 < 6 - 1 which is correct.

Then from the other side of the line I picked (5,2)

2 < -2 (5) - 1

2 < -10 - 1

2 < -11 is not true so the inequality that we found was correct.

   // An object of type Integer is declared with initial value of 1

   Integer newInt = new Integer(1);

   // The value of the new declared and assigned object is displayed to the user

   System.out.println(newInt);

   // The new declared object is assigned to the reference variable myInt

   myInt = newInt;

   // The value of myInt is displayed to the user
