Answer:

Solution of the equation 2|x +7|-3=5 is :

x1 = - 11 and x2 = - 3

Answer:

  x = -3 and x = -11

Step-by-step explanation:

Find the "bare" absolute value function, then solve the two resulting equations.

  2|x+7| -3 = 5

  2|x +7| = 8 . . . . . add 3

  |x +7| = 4 . . . . . . divide by 2

This resolves to two equations:

  x +7 = 4

  x = -3 . . . . . subtract 7

and

  x +7 = -4

  x = -11 . . . . . subtract 7

The two solutions are ...

  x = -3 and x = -11

Answer:

The answer is -7, or x = -7.

Answer:

Step-by-step explanation:

The required simplified form of the given expression 3+ (3 - 8)² - 7 is 21.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

The given expression is below as:

3+ (3 - 8)² - 7

To simplify the given expression, we need to follow the order of operations. The order of operations is a set of rules that dictate the order in which arithmetic operations should be performed. The order of operations is often abbreviated as PEMDAS:

P: Parentheses first

E: Exponents (ie Powers and Square Roots, etc.)

MD: Multiplication and Division (left-to-right)

AS: Addition and Subtraction (left-to-right)

So, we start by simplifying the expression within the parentheses first:

3+ (3 - 8)² - 7

3+ (-5)² - 7

3+ 25 - 7

Next, we simplify the exponents:

3+ 25 - 7

3+ 25 - 7

Then, we simplify the multiplications and divisions, working from left to right:

3+ 25 - 7

3+ 25 - 7

Finally, we simplify the additions and subtractions, working from left to right:

3+ 25 - 7

28 - 7

The simplified expression is:

28 - 7

= 21

Therefore, the simplified form of the given expression is 21.

Answer:

[tex]20*4[/tex]

Step-by-step explanation:

Han's team has 4 players.

A perfect score is the maximum possible score. Each player can score up to 20 points in each round, so 20 points is the maximum score.

If each of the 4 players scores 20 points, then the total score for the team is:

[tex]20*4[/tex]

That is the expression for the team's points.

Answer: [tex]20*4[/tex]

The expression that represents the number of points that Han's team earns in one round if every player earns a perfect score is 20 × 4.

Maximum point that each player can get = 20

Number of people in Han's team = 4

Therefore, the expression that will represent the number of points that Han's team earns in one round if every player earns a perfect score will then be:

= 20 × 4

= 80

Step 3:

3 1/3 ÷ 5/9   Divide

Step 4:

10/3 × 9/5    Convert and Multiply

Answer:

x = 6

Hope This Helps :)

The solution to the equation (5/9)x - 1/3 = 3 is x = 6.

We have,

To solve the equation (5/9)x - 1/3 = 3 for x, we can follow these steps:

Step 1: Add 1/3 to both sides of the equation to isolate the term with x:

(5/9)x - 1/3 + 1/3 = 3 + 1/3

This simplifies to:

(5/9)x = 3 + 1/3

Step 2: Combine the fractions on the right side of the equation:

(5/9)x = 10/3

Step 3: Multiply both sides of the equation by the reciprocal of (5/9), which is (9/5), to solve for x:

((9/5) * (5/9))x = (10/3) * (9/5)

Simplifying further:

1x = (90/15)

Step 4: Simplify the fraction on the right side of the equation:

x = 6

Therefore,

The solution to the equation (5/9)x - 1/3 = 3 is x = 6.

Answer:

If you multiply any irrational number by the rational number zero, the result will be zero, which is rational. Any other situation, however, of a rational times an irrational will be irrational.

Answer: x = −2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3(x−5)−3=5(x−2)+2x

(3)(x)+(3)(−5)+−3=(5)(x)+(5)(−2)+2x(Distribute)

3x+−15+−3=5x+−10+2x

(3x)+(−15+−3)=(5x+2x)+(−10)(Combine Like Terms)

3x+−18=7x+−10

3x−18=7x−10

Step 2: Subtract 7x from both sides.

3x−18−7x=7x−10−7x

−4x−18=−10

Step 3: Add 18 to both sides.

−4x−18+18=−10+18

−4x=8

Step 4: Divide both sides by -4.

-4x / -4 = 8 / -4

[tex]V_{sm}=475.4\ ft^3[/tex]

Step-by-step explanation:

Hemisphere

It's defined as half of a sphere. The volume of a sphere is:

[tex]\displaystyle V_s=\frac{4}{3}\pi r^3[/tex]

Thus, the volume of a semisphere is half of that:

[tex]\displaystyle V_{sm}=\frac{2}{3}\pi r^3[/tex]

We know the radius is r=6.1 ft, thus:

[tex]\displaystyle V_{sm}=\frac{2}{3}\pi\cdot (6.1)^3[/tex]

[tex]V_{sm}=475.38789\ ft^3[/tex]

Answer:

Step-by-step explanation:

Given that :

Initial Position of dive ring = 10 feets below the water surface = - 10 feets

Final position of dive ring = water surface

Distance moved to arrive at final position:

0 - (-10) = 0 + 10 = 10 feets

Hence, final position with respect to the surface of water :

Initial Position + distance moved

-10 feets + 10 feets

Hence, the final position = 0, with respect to the surface of water.

Answer:

4x- 2

Step-by-step explanation:

if you're asked perimeter simply add the length of sides of the finger

p= (x+ 3)+ (2x- 5) + (x)

p= 4x- 2

The solution to the inequality -1.5(4x + 1) > 4.5 -2.5(x + 1) is x > 7/16.

Start by simplifying the expressions on both sides of the inequality:

-1.5(4x + 1) = -6x - 1.5

and

4.5 - 2.5(x + 1) = 4.5 - 2.5x - 2.5

Now that the expressions are simplified, substitute them back into the inequality:

-6x - 1.5 > 4.5 - 2.5x - 2.5

Solve for x by adding 2.5x to both sides and subtracting 4.5 from both sides:

-3.5x > 1

0.5x > 1

Finally, divide both sides by 0.5 to get:

x > 2

So the solution set is x > 2.
