Answer:

x= -8/3

Step-by-step explanation:

(x-6)-(x+2)=3x

step 1) remove parentheses

x-6-x-2=3x

step 2) combine like terms

-8=3x

step 3) solve for x by dividing by 3 on both sides

-8/3 = x

Answer:

See below

Step-by-step explanation:

Hi there!

We want to solve the following equation:

(x-6)-(x+2)=3x

In this equation, notice how in front of (x+2), there is a minus sign

It's the same as if the equation was:

(x-6) + -1(x+2)=3x

We'll need to distribute the -1 to both terms, x and 2

so:

-1(x+2)= -1*x + -1*2= -x + -2, or -x-2

As for the (x-6), we can just open up the parenthesis without doing anything.

So on the left side, it becomes:

x -6 -x -2 = 3x

Now we can combine like terms.

x and -x are like terms, while -6 and -2 are like terms

x and -x add up to equal 0, while -6 and -2 add up to equal -8

-8 = 3x

Now, we have 3x by itself, but remember we just want x, or 1x.

Dividing a number by itself will result in 1

So we can divide both sides by 3

*note: we shouldn't divide by 3x. When we divide by 3, the result is [tex]\frac{3x}{3}[/tex], which if we cancel out the 3 from the numerator and denominator, gets the same result as 1x. If we divided by 3x, we'd just be getting 1 on the right side, while we'd be getting [tex]-\frac{8}{3x}[/tex] on the left, which isn't what we want.

-8/3=x

Hope this helps!

Answer:

Step-by-step explanation:

Pythagoras simply says that for a right triangle, the sum of the squares of the two shorter legs will equal the square of the hypotenuse.

a² + b² = c²

in this case a = x

                  b = x + 2

                   c = x + 3

x² + (x + 2)² = (x + 3)²

x² + (x + 2)² = (x + 3)²

x² + (x² + 4x + 4) = (x² + 6x + 9)

       2x² + 4x + 4 = x² + 6x + 9

           x² - 2x - 5 = 0

quadratic formula

x = (2 ±√(2² - 4(1)(-5))) / (2(1))

x = (2 ± √24) / 2

a negative length does not make sense so

x = 1 + √6

     x ≈ 3.4

x + 2 ≈ 5.4

x + 3 ≈ 6.4

Answer:

361/900

Step-by-step explanation:

First, multiply 0.6 by (-1/3) to get -0.2 which equals (-1/5).

Now the equation is [tex](-\frac{1}{6}-0.2+1 )^{2}[/tex]

Next, solve the inside of the parenthesis [tex]-\frac{1}{6}-\frac{1}{5} +1 = \frac{19}{30}[/tex]

Now the equation is [tex](\frac{19}{30})^{2}[/tex]

Finally we square this to get the simplified fraction of [tex]\frac{361}{900}[/tex]

Answer:

£140 : £210

Step-by-step explanation:

sum the parts of the ratio, 2 + 3 = 5 parts

Divide the total by 5 to find the value of one part

£350 ÷5 = £70 , then

2 parts = 2 × £70 = £140

3 parts = 3 × £70 = £210

£350 in the ratio 2 : 3 is £140 : £210

Answer:

-14

Step-by-step explanation:

Step 1 :- Distribute 2 through parantheses.

Step 2 :- Divide the number in the brackets.

Step 3 :- When there is a + in the front of an expression in parantheses, the expression remains the same .

Step 4 :- Calculate the difference.

Therefore , the answer of this expression is -14.

Answer:

52.6

Step-by-step explanation:

263/5=52.6

Answer:

53

Step-by-step explanation:

You must take 263 and divide it by 5

263/5 = 52.6

So, 5 times 52 = 260

BUT 5 times 53 = 265.  You would need 53 fish bowls

Answer:

  0 (US) or 90.870 (some other places)

Step-by-step explanation:

We can see this problem being interpreted two ways, depending on the number conventions you're using.

US interpretation

In this interpretation, the decimal point separates the integer and fractional parts of a decimal number.

You want the nearest ten thousand to ninety and a fraction. Since ninety is less than five thousand, it rounds to zero.

  90.872 ≈ 0

__

French interpretation (and some other places)

In this interpretation, the comma separates the integer and fractional parts of a decimal number.

You want the nearest ten to ninety thousand eight hundred seventy-two. Since two (the units digit) is less than five, it is replaced by zero.

  90.872 ≈ 90.870

Answer:8

Step-by-step explanation:

Answer:

If you substitute x with 88/9, you will get the answer as 75 with is correct.

Step-by-step explanation:

convert 6 into a fraction

54/9

9(88/9-54/9) +41

subtract 88/9-54/9

use this formula

a/c - b/c = (a - b)÷ c

88/9- 54/9 = (88-54)÷ 9

= 34/9

9(34/9)+41

convert 9 to a fraction

81/9

81/9(34/9) + 41

multiple

81/9(34/9) using this formula

a/b × c/d. = (a×c) ÷( b×d)

81/9(34/9)= (81×34) ÷(9×9) = 2754÷81

2754/81 + 41

reduce 2754/81

= (2754÷81) ÷ (81÷81)

34/1

= 34

34+41 = 75

Since y is not equal to 10, hence the coordinate point does not fall on the line graph.

Since we are not given a graph, we will use the attached graph as a reference:

The equation of a line is expressed as y = mx + b

m is the slope

b is the y-intercept

Get the slope of the line

[tex]m = \frac{0-(-2)}{-2-0}\\m=\frac{2}{-2}\\m = 1[/tex]

Since the line suts the y-axis at y = -2, hence b = -2

Get the equation of the line:

Recall that y = mx + b

y = x + (-2)

y = x - 2

Next is to check if the coordinate (5, 10) lies on the line

If x = 5

y = x - 2

y = 5 - 2

y = 3

Since y is not equal to 10, hence the coordinate point does not fall on the line graph.

Answer:

900 Large Fish

1500 Fish Total

Step-by-step explanation:

The 2:3 ratio means that for every 2 small fish sold, 3 large fish are sold.

We can divide 600 by 2 and then multiply by 3 to find our answer.

[tex]3(\frac{600}{2} )[/tex]

[tex]3(300)[/tex]

[tex]900[/tex]

To check our answer, we can put it into the form of a fraction and see if it simplifies back to that ratio.

[tex]\frac{600}{900} /\frac{300}{300} =\frac{2}{3}[/tex]

We have confirmed 900 is the correct number of large fish. To answer the second part of the question we just have to add the two numbers together.

[tex]600+900=1500[/tex]

So, our two answers are

900 Large Fish

1500 Fish Total

Step-by-step explanation:

there must be something missing in the problem text and/or answer options.

because based on what is visible here, the only answer is infinite (real or any other type) solutions.

an expression that is always true (like here 16>0) stays true for any values for any variables you can think of.

therefore, infinite possibilities with that expression being true.
