Answer:

b = 9

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20-b\\\frac{2}{3} b+5+b=20-b+b\\\frac{5}{3} b+5=20\\\frac{5}{3} b+5-5=20-5\\\frac{5}{3}b=15\\b= 15*\frac{3}{5} \\b= 9[/tex]

Answer:

[tex]b = 9[/tex]

Step-by-step explanation:

[tex]\frac{2}{3} b + 5 = 20 - b[/tex]

In order to solve for b, we must isolate the variable. We can start by subtracting 5 from both sides.

[tex]\frac{2}{3} b + 5 - 5 = 20 - b - 5[/tex]

Simplify.

[tex]\frac{2}{3} b = 15 - b[/tex]

Add b to both sides.

[tex]\frac{2}{3} b + b = 15 - b + b[/tex]

Simplify.

[tex]\frac{2}{3} b + b = 15[/tex]

Multiply everything by 3 to remove the fractions.

[tex]3(\frac{2}{3}b+b) = 3(15)[/tex]

Simplify.

2b + 3b = 45

Simplify.

5b = 45

Divide 5 from both sides.

5b ÷ 5 = 45 ÷ 5

Simplify.

b = 9

Answer:   3(6a+5)

We can confirm this by distributing the 3 back in

3*6a = 18a

3*5 = 15

So 3(6a+5) = 3*6a+3*5 = 18a+15

The process of factoring polynomials like this is basically using the distributive property in reverse.

Answer:

3(6a + 5)

Step-by-step explanation:

1)  Find the Greatest Common Factor (GCF).

1 - What is the largest number that divides evenly into 18a and 15?

It is 3.

2 - What is the highest degree of a that divides evenly into 18a and 15.

It is 1, since a s not in every term.

3 - Multiplying the results above,

The GCF is 3.

2) Factor out the GCF. (Write the GCF first. Then, in parentheses, divide each term by the GCF.)

3 (18a/3 + 15/3)

3)  Simplify each term in parentheses.

Step-by-step explanation:

its the right answer

If triangles AMN and ABC are similar, then

AM/AB = AN/AC

or

AM/(AM + MB) = AN/(AN + NC)

Check if this is true:

AM/AB = 21/(21 + 9) = 21/30 = 7/10

AN/AC = 14/(14 + 6) = 14/20 = 7/10

The angle at vertex A is common to both of the triangles.

Then by the side-angle-side (SAS) similarity theorem, the triangles are indeed similar.

Answer:

  a.  $19,224.92

Step-by-step explanation:

The dealer's cost will be the sum of the dealer's costs for the base car, its options, and the destination charge.

__

  cost for base car = 0.83 × $21,276 = $17,659.08

  cost for options = 0.80 × $1,219.80 = $975.84

  cost for destination charge = $590.00

The sum of the dealer's costs is ...

  $17,659.08 +975.84 +590.00 = $19,224.92

Barrons should estimate the dealer's cost to be $19,224.92.

Answer: c

Step-by-step explanation:

The required values on the graph, the solution is approximate x = -0.33.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

To solve this equation, we can begin by combining like terms on the left-hand side:

3x² - 6x - 4 - 2/x + 3 + 1 = 0

3x² - 6x - 2/x = -3

Next, we can factor out the x term:

x(3x - 2) - 2(3x - 2) = -3

(x - 2)(3x - 2) = -3

Since the equation is equal to -3, we can add 3 to both sides to get:

(x - 2)(3x - 2) + 3 = 0

We can then factor the left-hand side to get:

(x - 2)(3x - 2 + 3) = 0

(x - 2)(3x - 2 + 3) = (x - 2)(3x + 1) = 0

This equation has two solutions: x = 2 and x = -1/3.

Approximating these values on the graph, we see that the solution is approximate x = -0.33.

Answer:

Step-by-step explanation:

We will look for a line that has the general form of y = mx + b, where m is the slope and b the y-intercept (the value of y when x = 0).

A line parallel to y=2x-1 will have the same slope, 2.

We can write y = 2x + b for the new line.  We need to find b.  We can use the given point in this equation and solve for b:

y = 2x + b

2 = 2(4) + b  for (4,2)

2 = 8 + b

x = -6

The parallel line to y=2x-1 that goes through point (4,2) is:

y = 2x-6

We are asked to write the equation of the line that passes through (4, 2) and is parallel to y=2x-1.

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

Since the slope of the given line is 2, the slope of the line parallel to this one is also 2.

y=2x+c

Where: 2 is the y-coordinate of the point, and 4 is the x-coordinate.

Now, substitute 2 for y and 4 for x:

[tex]\longmapsto\sf{2=2(4)+c}[/tex]

Simplify!

[tex]\longmapsto\sf{2=8+c}[/tex]

Subtract 8 from both sides of the equal sign:

Step-by-step explanation:

Analyzing the quadratic functions, it is found that the correct option is D. The functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Looking at the graph, Function f has a minimum value of 1 at x = -3. Hence, the axis of symmetry is x = -3.

Function g has a minimum value of 6 at x = -3. Hence, the axis of symmetry is also x = -3.

Therefore, the functions f and g have the same axis of symmetry, but the minimum value of f is less than the minimum value of g.

Answer:

divide the number of people supporting the home team by the percentage supporting the home team.

1413/0.45 = 3140

total people = 3,140

The total number of people attending the basketball game was 3140.

Let's denote the total number of people attending the game as "T."

According to the information given, 45% of the people were supporting the home team. Therefore, the number of people supporting the home team can be calculated as 45% of the total number of people: 0.45 * T.

We are also told that 1413 people supported the home team. So, we can write the equation:

0.45 * T = 1413

Now, let's solve for the total number of people attending the game (T):

T = 1413 / 0.45

T = 3140

Therefore, the total number of people attending the basketball game was 3140.

Answer:

98.4 inches

Step-by-step explanation:

1 meter is about 3.28 ft, meaning the oak tree is 8.2ft tall. (2.5*3.28)

1 foot is 12 inches, meaning the oak tree is 98.4 in tall. (8.2*12)

The height of the oak tree = 98.42 inches.

Given that,

The height of the oak tree is 2.5 meters

We have to find height of tree in inches.

Since we know that,

A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.

Since we know that,

1 meter = 39.37

Then to find the height of oak tree in inches

Multiply 2.5 with 39.37

Therefore,

The height of the oak tree in inches = 2.5 x 39.37

Answer:

Option D - x = 3 3/5

Step-by-step explanation:

Lets make the left side into an improper fraction :

2 2/5 = 12/5

Now let's make both fraction into equivalent ones but with the same denominator :

2/3 = 10/15

12/5 = 36/15

Now we substitute the equivalent values back into the equation :

10/15 × x = 36/15

Now we multiply both sides by 15 to remove the denominators:

10 × x = 36

Now we divide both sides by 10 and simplify :

x = 36/10

x = 18/5

x = 3 3/5

So our answer will be Option D
