Solve the following equation. Then determine if the equation is an identity or a contradiction.2(3n + 3) - 9 = 6n

Answers

Answer 1

Answer: Let's solve the equation step by step:

1. Start with the equation: $2(3n+3)-9=6n$.

2. First, distribute the 2 on the left side of the equation:
$6n + 6 - 9 = 6n$.

3. Next, simplify the equation by combining like terms. The 6n on both sides can be canceled out:
$6 - 9 = 0$.

4. Simplify further:
$-3 = 0$.

Now, let's analyze the result:

The equation $-3 = 0$ is a contradiction. This means that there is no value of $n$ that will satisfy the equation. In other words, there is no solution to this equation.

5x+y=2 2x3y=62
whatn is x and y

Answers

5x + y = 2 ⇒ 10x + 5y = 4
2x + 3y = 62 ⇒ 10x + 15y = 310
         -10y = -306
      -10 -10
   y = -30.6
      5x - 30.6 = 2
   +30.6 +30.6
      5x = 32.6
   5 5
      x = 6.52
   (x, y) = (6.52, -30.6)

ok sure!
first we have to find y

so...
lets start with the first one:

5x+y=2 (we cannot have two variables together so:
5x+y=2
-y =-y so.. now we have 5x= 2-y (but we must get y positive and by itself!)
-2 = -2
so: now you have
5x-2=-y but need a positive variable so multiply each side by a (-1)
(-1) 5x-2=-y (-1) So..
-5x +2 =y so now we know Y!
therefore whenever you see why in the next problem insert in its place: -5x +2

I hope it helps!! :)

The volume of a cone is 258.9 cubic centimeters. a cylinder has the same base and height as the cone. what is the volume in cubic centimeters of the cylinder

Answers

Volume of a cylinder = A(base)*height

Volume of a cone = 1/3*A(base)*height

Because the base and height of the cylinder and cone are the same, we can write

Volume of the cone = 1/3*A(base)*height =1/3*Volume of the cylinder

Volume of the cone = 1/3*Volume of the cylinder, so

Volume of the cylinder=3*Volume of the cone =3*258.9=776.6 cm³

Volume of the cylinder= 776.6 cm³

Answer:

776.7 cm^3

You have 1/2 pound of flour. You split up the flour into 3 bags so each bag weighs the same. Which of these statements is NOT true?A. Each bag has 1/3 of the flour.
B.1/2 pound is 3 times as heavy as each bag of flour.
C.Each bag has 1/3 pound of flour.
D.Each bag has 1/6 pound of flour.

Answers

Given:
1/2 pound of flour
split the flour into 3 bags of equal weight.

1/2 ÷ 3

In dividing fractions, you must remember to get the reciprocal of the 2nd fraction and multiply it to the 1st fraction.

3 is the 2nd fraction. Its reciprocal is 1/3

1/2 * 1/3 = 1/6 pound of flour.

The False statement is:
C. Each bag has 1/3 pound of flour.
