Step-by-step explanation:
[tex]\frac{1}{2}(7.5cm * x) = 1500m^2 \\\frac{1}{2}(7.5cm * x) = 150,000cm^2 \\7.5cm * x = 300,000cm^2 \\x = 40,000 cm^2\\x = 400 m^2[/tex]
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.

If BD=7x-10, BC=4x-29,and CD=5x-9 what is x ?
Answers
From the question, we know that the sum of BC and CD equals BD.
BD = BC + CD = 7x - 10
BC = 4x - 29
CD = 5x - 9
Let's set BC and CD equal to BD
4x - 29 + 5x - 9 = 7x - 10
Combine like terms on the left side.
9x - 38 = 7x - 10
Add 38 to both sides and subtract 7x from both sides.
2x = 28
Divide both sides by 2
x = 14

Step-by-step explanation:

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.

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.
