3(x+2) = 2x+3

3x + 6 = 2x + 3

3x + 6 - 2x = 2x +3 - 2x

X+6 = 3

X+6 - 6 = 3-6

x = -3

Answers

Answer 1

Answer:

Distribution is used from steps 1-2

They eliminate 2x by subtracting it on both sides (steps 3-4)

They eliminated 6 by subtracting it from both sides (steps 5-6)

(steps 3-6 is eliminating like-terms)

Thus this leaves the answer being x=-3

Step-by-step explanation:

Answer 2

Equation 3(x+2) = 2x+3 solved using distributive property and simplification, final solution is x = -3.

Let's identify the reason for each step in the solution to the equation 3(x+2) = 2x+3:

Distributive Property

The first step applies the Distributive Property,

which states that multiplying a number outside the parentheses by the terms inside the parentheses.

Here, we multiply 3 by (x+2),

3(x+2)

= 3 × x + 3 ×2

= 3x + 6

Combining Like Terms

In the second step, combine like terms on both sides of the equation.

On the left side, we have 3x, and on the right side, we have 2x.

We also have constants 6 on the left side and 3 on the right side.

3x + 6 = 2x + 3

Move Variables to One Side

To solve for 'x', we want all the terms with 'x' on one side of the equation.

Here,  move the term with 2x to the left side by subtracting 2x from both sides of the equation:

3x + 6 - 2x = 2x + 3 - 2x

Simplify

On the left side, the term 2x cancels out with the 2x on the right side, leaving us with:

x + 6 = 3

Move Constants to the Other Side

To isolate 'x', we need to get rid of the constant term on the left side.

Subtracting 6 from both sides of the equation:

x + 6 - 6 = 3 - 6

Simplify

On the left side, the +6 and -6 cancel out, leaving us with:

x = -3

Final Solution

After simplifying, find that the value of 'x' that satisfies the original equation is x = -3.

This means that if we replace 'x' with -3 in the equation, it will hold true:

3(-3 + 2) = 2(-3) + 3

-3 = -6 + 3

-3 = -3

And that's why the solution to the equation is x = -3.

Therefore, the reason required for solving the equation are distributive property and simplification which gives solution is x = -3

A body is floating in seawater with 2/3 of its volume above the surface. The weight of the displaced water is?

Answers

Answer:

The weight of the displaced water is the weight of the body

Step-by-step explanation:

In situations like this, the volume of the displaced water is not important.

However, it should be noted that when a body is immersed (fully or partially) in a liquid, the weight of the displaced liquid is equal to the weight of the body immersed in the liquid.

Since the weight of the body is not given, I'll conclude that the displaced water has the same weight as the body floating on the water.

Identify if each given value is a zero of the equation 0=18c3−50c

The only zero of the equation 0=18c³−50c is c = 0, as it makes the equation true when substituted.

value is a zero of the equation 0 = 18c³ - 50c,

putting in the value for c

If c = 0:

0 = 18(0)³ - 50(0)

0 = 0 - 0

0 = 0 (True)

If c = 2:

0 = 18(2)³ - 50(2)

0 = 18(8) - 100

0 = 144 - 100

0 = 44 (False)

If c = -1:

0 = 18(-1)³ - 50(-1)

0 = 18(-1) + 50

0 = -18 + 50

0 = 32 (False)

only c = 0 is a zero of the equation 0 = 18c³ - 50c.

The equation 0 = 18c³ - 50c has only one zero, which is c = 0, as it satisfies the equation when substituted.

Question 4 options:

Answers

Answer:

83/90

Step-by-step explanation:

you need to multiply the variable by 10. x =

0.9222… 10x = 9.222… 10x – x = 9.222… – 0.9222… 9x = 8.3 x =83/90

The decimal 0.92¯¯¯ is equal to the fraction 92/99.

So, the correct answer is 92/99.

Given that, a decimal 0.92¯¯¯, we need to convert it into fraction,

To convert the decimal 0.92¯¯¯ to a fraction, we can follow these steps:

Let's represent 0.92¯¯¯ as x.

Step 1: Multiply x by 100 to remove the repeating decimal:

100x = 92.92¯¯¯

Step 2: Subtract x from 100x to eliminate the repeating decimal:

100x - x = 92.92¯¯¯ - 0.92¯¯¯

99x = 92

Step 3: Divide both sides of the equation by 99 to solve for x:

x = 92/99

Therefore, the decimal 0.92¯¯¯ is equal to the fraction 92/99.

So, the correct answer is 92/99.
