Simplifying

12x + 10 + 3 + 8x = 0

Reorder the terms:

10 + 3 + 12x + 8x = 0

Combine like terms: 10 + 3 = 13

13 + 12x + 8x = 0

Combine like terms: 12x + 8x = 20x

13 + 20x = 0

Solving

13 + 20x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + 20x = 0 + -13

Combine like terms: 13 + -13 = 0

0 + 20x = 0 + -13

20x = 0 + -13

Combine like terms: 0 + -13 = -13

20x = -13

Divide each side by '20'.

x = -0.65

Simplifying

x = -0.65

Greetings!

First off, we should know that there are 60 minutes in an hour. Therefore, the first step we will need to do, is divide 60 by 10.

60 ÷ 10 = 6

As shown above, we now know we will have to double the number 6 times. If we start with 30, this will be our first problem.

(1)   30 + 30 = 60

And so on and so forth...

(2)   60 + 60 = 120

(3)   120 + 120 = 240

(4)   240 + 240 = 480

(5)   480 + 480 = 960

(6)   960 + 960 = 1920

And after our sixth time we have our answer:

1920 bacteria

Step-by-step explanation:

I don't know exactly how simplified it will be, but you can get the square root smaller.

180: 2*2 * 3*3 *5

For every pair of prime factors you can take 1 of the pair outside the the square root and throw the other one away

sqrt(2*2*3*3*5) = 2 * 3 * sqrt(5) = 6*sqrt(5)

Answer: The comic book was $3.

Step-by-step explanation:

Instead of 5x=8, it should have been 5+x=8 because he only purchased a single comic book. Subtract 5 from 8 and your X value is 3.

Answer:

Liam spent $3 on the book.

Step-by-step explanation:

Liam bought a comic book and had $5 left.

He had a total of $8 walking into the store, so he spent [tex]8-5=3[/tex] dollars on the comic book.

Liam used the equation 5x=8 to model the problem.

This is wrong. The correct form would have been [tex]8-x=5[/tex] or [tex]5+x=8[/tex] where x represents the amount of money he spent.

Hence, Liam spent $3 on the book.

Answer:

14/18 = 0.778

Step-by-step explanation:

14 divided by 2 = 7

18 divided by 2 = 9

7/9 is the same as 7 divided by 9

= 0.778

The decimal equivalent of [tex]\( \frac{14}{18} \)[/tex] is approximately 0.777777777777778.

To convert [tex]\( \frac{14}{18} \)[/tex] to a decimal, one divides 14 by 18. This can be done by hand or with a calculator. When dividing 14 by 18, the result is a repeating decimal where the digit 7 repeats indefinitely. This repeating decimal can be represented as 0.777777777777778 when rounded to the nearest 10th decimal place.

Alternatively, one can simplify the fraction [tex]\( \frac{14}{18} \)[/tex] before converting it to a decimal. By dividing both the numerator and the denominator by their greatest common divisor, which is 2, the fraction simplifies to [tex]\( \frac{7}{9} \)[/tex]. When 7 is divided by 9, the result is again the repeating decimal 0.777777777777778.

In summary, [tex]\( \frac{14}{18} \)[/tex] simplifies to [tex]\( \frac{7}{9} \)[/tex] and as a decimal, it is approximately 0.777777777777778.

Answer:

y=3x-5

Step-by-step explanation:

parallel means that both lines share the same gradient.

from the equation y=3x-12 , we can deduce that the gradient is 3 because it is in the gradient-intercept form

now substitute values into formula

y-y1=m (x-x1)

y--2=3 (x-1)

expand brackets and simplify

y+2=3x-3

subtract 2 from both sides of equation

y=3x-5

Answer:

[tex]y = 2x + 3[/tex]

Step-by-step explanation:

First, we can find the slope of the line.

[tex]m = \frac{y1-y2}{x1-x2}\\m=\frac{9-5}{3-1}\\m = \frac{4}{2}=2\\[/tex]

Using the [tex]y = mx + b[/tex] equation, we can solve for b

[tex]9 = 2(3)+b\\9 = 6 + b\\b = 9-6 = 3[/tex]

Let's see if [tex]y = 2x + 3[/tex] works

[tex]2(1) + 3 \\2 + 3 = 5\\\\2(3) + 3\\6 + 3 = 9[/tex]

Answer:

The fraction number is [tex]\frac{34}{9}[/tex]

Step-by-step explanation:

we have

[tex]3.777...[/tex]

This is a repeating decimal  (a decimal that has a digit, that repeat over and over and over again without ever ending)

Convert to fraction number

Let

[tex]x=3.777...[/tex]

[tex]10x=37.777...[/tex]

we know that

[tex]10x-x=37.777...-3.777...[/tex]

[tex]9x=34[/tex]

[tex]x=\frac{34}{9}[/tex]

therefore

The fraction number is [tex]\frac{34}{9}[/tex]

Answer:

$42.05

Step-by-step explanation:

Take $96.00 from 1,584.19 to figure out how much he had before he deposited

1,584.19 - 96 = 1,488.19

Now take away what he had after he took 96, to after he added.

1,530.24 - 1,488.19 = 42.05

Answer:

-6

Step-by-step explanation:

[tex] | - 2| = 2 \\ {( - 2)}^{3} = ( - 2)( - 2)( - 2) = ( - 8) \\ \\ | - 2 | + {( - 2)}^{3 } = 2 - 8 = - 6[/tex]

To evaluate the expression |b|+b^3 when b=-2, substitute -2 for b, evaluate |b| and b^3 separately and then add the results.

To evaluate the expression |b|+b^3 when b=-2, we substitute -2 for b in the expression.

The absolute value of a number is that number's distance from zero on a number line, regardless of which direction. This means that the absolute value of any negative number is its positive equivalent. Thus, |b| is the same as |-2|, which equals 2.

Secondly, b^3 means b multiplied by itself twice. So (-2)^3 equals -2*-2*-2 which is -8.

First, we evaluate |b|. The absolute value of -2 is 2, so |b| = 2.

Next, we evaluate b^3. (-2)^3 = -8.

Finally, we add the two results together: 2 + (-8) = -6.

Therefore, when b=-2, the expression |b|+b^3 evaluates to -6.

Answer:

x=-y

Step-by-step explanation:

Answer:

2x-4 = 22

2x = 26

x=13 check |26-4|=22

-(2x-4) = 22

-2x+4 = 22

-2x = 18

x=-9 Check |-18 -4| = |-22| = 22

Answer:

x=13

Step-by-step explanation:

Finding the answer to this is very simple actually. you can actually solve this problem without the || because x has to be a positive value for this to work. 2x-4=22 can be done by adding 4 to both sides and getting the answer 26. Isolate the variable by dividing both sides by 2 to get x=13

Step-by-step explanation:

Solve for Y:

Y - 9 = 41

Add 9 to both sides:

Y + (9 - 9) = 9 + 41

9 - 9 = 0:

Y = 41 + 9

41 + 9 = 50:

Answer:  Y = 50

Answer:

Y=50

Step-by-step explanation:

First you have to know that whatever you do to one side of the equal sign you must do to the other. Now you want to try and get rid of the 9 so you can separate the variable.

Y-9=41

Step-by-step explanation:

12 ten-thousands = 12*10000=120,000.

8 thousands = 8*1000=8000;

this gives us 120,000+8,000=128,000.

14 hundreds = 14*100=1400;

this gives us 128,000+1,400=129,400.

7 ones = 7*1=7;

Answer:

13 plants.

Step-by-step explanation:

We have been given that Malachi’s garden is 2 3/5 meters long. He wants to plant tomato plants every 1/5 of a meter.

To find the number of tomato plant that will fit the garden, we will divide length of garden by 1/5 as:

[tex]\text{Number of tomato plant that will fit the garden}=2\frac{3}{5}\div \frac{1}{5}[/tex]

Convert mixed fraction into improper fraction:

[tex]2\frac{3}{5}\Rightarrow\frac{2\times5+3}{5}=\frac{10+3}{5}=\frac{13}{5}[/tex]

[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\div \frac{1}{5}[/tex]

Convert to multiplication problem by flipping the 2nd fraction:

[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{5}\times \frac{5}{1}[/tex]

[tex]\text{Number of tomato plant that will fit the garden}=\frac{13}{1}\times \frac{1}{1}[/tex]

[tex]\text{Number of tomato plant that will fit the garden}=13[/tex]

Therefore, 13 plants will fit Malachi's garden.

Answer:

2.91666667 ft

Step-by-step explanation:

2x - 3y = 3

x + 2y = 5

In the second equation we have an x-term that has a coefficient of 1 (which means the x is all by itself), so we can isolate that x and solve by substitution.

x + 2y = 5

x + 2y - 2y = 5 - 2y

x = 5 - 2y

The expression 5 - 2y will be substituted for x in the first equation.

2x - 3y = 3

2(5 - 2y) - 3y = 3

Solve for y.

2(5 - 2y) - 3y = 3

10 - 4y - 3y = 3 (distribute the 2)

10 - 7y = 3 (collect like terms)

-7y = -7 (subtract 10 from both sides)

y = 1 (divide both sides by -7)

Substitute 1 for y in the second equation to find x.

x + 2y = 5

x + 2(1) = 5

Solve for x.

x + 2(1) = 5

x + 2 = 5 (multiply)

x = 3 (subtract 2 from both sides)

Always check your work. Substitute into the original system.

2x - 3y = 3

2(3) - 3(1) = 3

6 - 3 = 3

3 = 3

x + 2y = 5

3 + 2(1) = 5

3 + 2 = 5

5 = 5

x = 3 and y = 1; (3,1)
