Answer: See below

Step-by-step explanation:

a.

To solve for h, we want to use algebraic properties to isolate h.

[tex]A=\frac{1}{2}h(b_1 +b_2)[/tex]                [multiply both sides by 2]

[tex]2A=h(b_1 +b_2)[/tex]                 [divide both sides by b₁+b₂]

[tex]\frac{2A}{b_1+b_2} =h[/tex]

[tex]h=\frac{2A}{b_1+b_2}[/tex]

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

b.

To solve for b₂, we first multiply both sides by 2. Then, we divide both sides by h. This leaves us with [tex]\frac{2A}{h} =b_1+b_2[/tex]. To get b₂, you subtract both sides by b₁.

Answer:

h=2A/(b1+b2)

and

b2=2A/h-b1.

Simon is making a poster about friendship in his art class. He divides his poster into 3 equal parts. Simon writes the names of his friends all over each part. Simon uses 1 part for his neighborhood friends and 1 part for his friends from school.
What fraction of the poster does Simon use for his friends from school?

Answers

Answer:

1/3

Step-by-step explanation:

The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.

Solve 3x -12 = 24.
Please help!

Answers

Answer:

12

Step-by-step explanation:

3x - 12 = 24

Add 12 to both sides to make 3x the subject of the equation.

3x - 12 (+12) = 24 (+12)

3x - 0 = 36

3x = 36

Divide both sides by 3.

3x/3 = 36/3

x = 12

Please give brainliest, rate 5 stars, and thank. Thank you

The required solution to the given equation 3x -12 = 24 is x = 12.

What is the algebraic equation?

Algebraic equations are mathematical statements with a minimum of two terms containing variables or numbers that are equal.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The given equation is given in the question

⇒ 3x - 12 = 24

Add 12 to both sides of the above equation

⇒ 3x - 12 (+12) = 24 (+12)

⇒ 3x - 0 = 36

Apply the subtraction operation,

⇒ 3x = 36

Divide both sides by 3.

⇒ 3x/3 = 36/3

⇒ x = 12

Therefore, the required solution to the given equation 3x -12 = 24 is x = 12.

Find variable of b + 25 = b —25

Answers

Answer:

There is no solution

Step-by-step explanation:

Simplifying

b + 25 = b + -25

Reorder the terms:

25 + b = b + -25

Reorder the terms:

25 + b = -25 + b

Add '-1b' to each side of the equation.

25 + b + -1b = -25 + b + -1b

Combine like terms: b + -1b = 0

25 + 0 = -25 + b + -1b

25 = -25 + b + -1b

Combine like terms: b + -1b = 0

25 = -25 + 0

25 = -25

Solving

25 = -25

Couldn't find a variable to solve for.

This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer:

There are no values of b no solution that makes the equation true.
