The weight of the walnuts alone is 360 pounds

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: 2x + 3 = 4 is an equation.

We have,

Number of craters of walnuts = 10

Weight of 10 craters of walnuts = 370 pounds

Weight of empty crate = 10 pounds

Weight of the 10 walnuts = M

Weight of the 10 walnuts + weight of the crater = 370 pounds

This can be written as an equation:

M + 10 = 370

Subtract 10 on both sides.

M = 370 - 10

M = 360 pounds

Thus,

The weight of the walnuts alone is 360 pounds

(X) =x3 to the function q(x-6)3-4

Answer:

The equation is 18h=378

h=21

Step-by-step explanation:

So first you have to set up the equation

so if she makes 18 dollars an hour the first part of the equation would be 18h

She made 378 dollars in one week so now the equation is 18h=378

The answer is h=21 because 378/18 is 21

The numbers in order

Answer:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

Step-by-step explanation:

We are given the function:

[tex]f(x)=3+|2x-5|[/tex]

Remember that by the definition of absolute value:

[tex]\displaystyle |x|= \left\{ \begin{array}{ll} x & \quad x \geq 0 \\ - x & \quad x < 0 \end{array} \right.[/tex]

Our absolute value is:

[tex]|2x-5|[/tex]

First, we will find when it becomes 0. Set the equation equal to 0:

[tex]2x-5=0[/tex]

Solve for x:

[tex]x=5/2[/tex]

So, we can see that for all values greater than x = 5/2, 2x - 5 is positive.

For all values less than x = 5/2, 2x - 5 is negative.

Therefore (the positive case go above, and the negative case go below):

[tex]|2x-5|= \left\{ \begin{array}{ll} 2x-5 & \quad x \geq 5/2 \\ -(2x-5) & \quad x < 5/2 \end{array} \right.[/tex]

Finally, we can add a three:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 3+(2x-5) & \quad x \geq 5/2 \\ 3+(-(2x-5)) & \quad x < 5/2 \end{array} \right.[/tex]

Simplify if desired:

[tex]f(x)=3+|2x-5|=\left\{ \begin{array}{ll} 2x-2& \quad x \geq 5/2 \\ -2x+8 & \quad x < 5/2 \end{array} \right.[/tex]

Answer:

x=20 hope this helps :)

The value of X is 20.

To find this answer, you must first find the least common denominator of both fractions. In this case, the LCD is 36.

Next, you multiply the left side by 4/4. The fraction 4/4 is simply found by dividing the right side denominator (36) by the left side denominator (9). 9 goes into 36 4 times.

5/9 * 4/4 = 20/36.

Thus meaning X = 20. I hope this helps!

Answer:

4.242;

$500.276 ; $46.724

Step-by-step explanation:

Given the regression equation :

value = -123.298 + 4.242 revenue

y = - 123.298 + 4.242x

y = team value ; x = Revenue

(a) What is the slope of this line?

From ;

y = mx + c

Where ; m = slope

Comparing the equation with, the model equation ;

mx = 4.242x ; Hence, slope, m = 4.242

(b) The HORNETS are the NBA's most valuable team, valued at $547 million, with $147 million in revenue. Use the line to predict the value of the HORNETS from their revenue.

Predicted value of hornets based on their revenue :

Revenue = $147,000,000

y = - 123.298 + 4.242(147)

y = - 123.298 + 623.574

y = 500.276

Predicted value is about $500.276 million.

What is the error in this prediction?:

Error = Actual - predicted value

Error = 547 - 500.276 = $46.724 million

Equation/Question:

1/2(x-106)=12+7x

Answer/Steps to answer: (x= -10)

1. Simplify  1/2(x-106) to x-106/2.

x-106/2=12 + 7x

2. Multiply both sides by 2.

x−106=24+14x

3. Subtract x from both sides.

−106=24+14x−x

4. Simplify  24+14x-x to  24+13x.

-106=24+13x

5. Subtract 24 from both sides.

-106-24=13x

6. Simplify  -106-24 to −130.

-130=13x

7. Divide both sides by 13.

130/13=x

8. Simplify  130/13 to  1010.

-10=x

9. Switch sides.

x=-10

-------------

Checking:

1/2(x−106)=12+7x

1. Let x=-10x=−10.1

1/2​(−10−106)=12+7×−10

2. Simplify -10-106 to −116.

1/2​×−116=12+7×−10

3. Move the negative sign to the left.

-116/2=12+7×−10

4. Simplify 116/2 to 58

−58=12+7×−10

5. Simplify 7×−10  to −70.

−58=12−70

6. Simplify  12-70 to −58.

−58=−58

Ratio of two numbers = 2:3

The larger number = 6

Let the smaller number be x.

Which means :

[tex] =\tt 2 : 3 \: = \: x : 6[/tex]

[tex] = \tt \frac{2}{3} = \frac{x}{6} [/tex]

[tex] =\tt 2 \times 6 = 3 \times x[/tex]

[tex] =\tt 12 = 3x[/tex]

[tex] =\tt x = \frac{12}{3} [/tex]

[tex]\hookrightarrow\color{plum}\tt \: x = 4[/tex]

▪︎Therefore, the smaller number = 4

36 compared to 6 = [tex] \tt \frac{36}{6} [/tex]

Let the number be x.

Which means :

[tex] = \tt \frac{36}{6} = \frac{x}{3} [/tex]

[tex] =\tt \frac{36 \div 2}{6 \div 2} = \frac{x}{3} [/tex]

[tex] =\tt \frac{36}{6} = \frac{18}{3} [/tex]

▪︎Therefore, the fractional number [tex] \tt \frac{18}{3} [/tex] is equal to [tex] \tt \frac{36}{6} [/tex].

Number of Rose's for 24 red Rose's = 6

This can be written in a ratio as 24:6

Number of roses = 8

Let the number of red roses for these roses be x.

Which means :

[tex] =\tt \frac{24}{6} = \frac{x}{8} [/tex]

[tex] =\tt 24 \times 8 = 6 \times x[/tex]

[tex] =\tt 192 = 6x[/tex]

[tex] =\tt x = \frac{192}{6} [/tex]

[tex]\hookrightarrow \color{plum}\tt x = 32[/tex]

▪︎Therefore, 32 red roses are there if there are 8 roses.

Number of children for 2 adults = 7

This can be written in a ratio as 7:2

Number of children in the plaza = 21

Let the number of adults be x.

Which means :

[tex] = \tt \frac{7}{2} = \frac{21}{x} [/tex]

[tex] =\tt7 \times x = 2 \times 21 [/tex]

[tex] =\tt 7x = 42[/tex]

[tex] =\tt x = \frac{42}{7} [/tex]

[tex] \hookrightarrow \color{plum}\tt \: x = 6[/tex]

▪︎Therefore, 6 adults were there in the plaza.

Cost of 12 pencils = P60

Cost of 1 pencil :

[tex] = \tt \frac{60}{12} [/tex]

[tex] =\tt P5[/tex]

Thus, the cost of one pencil = P5

Cost of 25 pencils :

= Cost of one pencil × 25

[tex] =\tt 5 \times 25[/tex]

[tex] \color{plum}=\tt \: P \: 125[/tex]

▪︎Therefore, the cost of 25 pencils = P125
