I CANT FIGURE OUT HELP ME!!! SOLVE FOR W: −(14w+8)+8=3

IM GIVING MAX POINTS I CAN!!!!!

Answers

Answer 1
Here are some things you should know when solving algebraic equations.

If you add an expression to both sides of an equation, the resulting equation will have the same solution set as the original equation. In other words, they will be equivalent. This is true for all operations. As long both sides are treated the same, the equation will stay balanced.

You will also need to know how to combine like terms. But what are like terms to begin with? Like terms are defined as two terms having the same variable(s) (or lack thereof) and are raised to the same power. In mathematics, something raised to the first power stays the same. So, 5x and 10x are like terms because they both have the same variable and are raised to the first power. You don’t see the exponents because it doesn’t change the value of the terms.

To combine like terms, simplify add the coefficients and keep the common variable(s) and exponent.

The distributive property is another important rule you will need to understand. The distributive property is used mostly for simplifying parentheses in expressions/equations. 
For example, how would you get rid of the parentheses here?

6(x + 1)

If there wasn’t an unknown in between the parentheses, you could just add then multiply. That is what the distributive property solves.

The distributive property states that a(b + c) = ab + ac
So, now we can simplify our expression.
6(x + 1) = 6x + 6
Now let's solve the equation you provided.

−(1\4w+8) + 8 = 3
-1\4w - 8 + 8 = 3 <-- Distribute the negative sign
-1\4w = 3 <-- Combine like terms
w = 3 ÷ [tex] -\frac{1}{4}[/tex]
w = -12

So, w is equal to -12.
Answer 2
-12 is the answer!
BOOM! lol

The area, a, of a trapezoid is calculated using the formula A= 1\2(b+c)h, where h is the height of the trapezoid and b and c are the base of the trapezoid. Rearrange the formula to solve for h

Answers

The answer is: h= (2A)/(b+c)
Final answer:

To rearrange the formula for the area of a trapezoid to solve for the height, divide both sides of the equation by (b+c)/2. The rearranged formula is h = 2A/(b+c).

Explanation:

The formula for the area of a trapezoid is given by A= 1/2(b+c)h, where A is the area, h is the height, and b and c are the lengths of the two bases. To rearrange this formula to solve for h (the height), you need to isolate h on one side of the equation. The rearranged formula would look as follows: h = 2A/(b+c).

To obtain this, we divided both sides of the equation by (b+c)/2. This gives us a new formula to find the height of the trapezoid given the area and the lengths of the two bases.

): How many times longer is the diameter of a grain of sand than the diameter of the average cell in the human body? Show your work.    Need help bad:(

Answers

Approximately 25. Of the 5 grades of sand used in the United states, medium sand has particles ranging from 0.25 mm to 0.5 mm. For convenience, I'll use 0.5mm as the diameter of a grain of sand. Human cells range from a volume of 30 cubic micrometers (human sperm cell) up to 4 million micrometers (human egg cell). For the average human cell, I'll use an osteoblast with a volume of 4000 cubic micrometers or a diameter of 2x10^-5 meters. Now just take the diameter of a grain of sand and divide by the diameter of a human cell. 5 x 10^-4 / 2x10^-5 = 5/2 x 10^(-4 - -5) = 2.5x10^1 = 25 So the diameter of a grain of sand at 0.5 mm is approximately 25 times larger than that of a human cell at 0.02mm

Solving Equations

Answers

For number 3 you'll add 5 to both sides and end up with the solution of a = -7
For number 4 you'll do the distribution property and get -4x-8=-40 then you'll add 8 to both sides and then divide by -4 on both sides and end up with the solution of x= 8
You start by trying to get the variable on one side. (Note:whatever you do to one side, you have to do to the other as well).
3. Add 5 on both sides, which will give you a= -7 (don't forget the negative sign)
For question 4 it's a bit different (Note: when you see a number next to a set of parentheses, that means you have to multiply the number by the parentheses AKA Distributive Property)
4. After distributing the -4, you'll get -4x-8=-40...but you're not done quite yet.
Now we have to get rid of the -8, so add 8 to each side, which will give us -4x=-32
Next divide each side by -4(because the number next to x is -4), once you do that, it'll leave you with x= 8 as your final answer.

0.6x-5=0.1x+7

Answers

0.6x - 5 = 0.1x + 7

0.6x - 0.1x = 5 + 7

0.5x = 12

0.5x/0.5 = 12/0.5

x = 24

hope this helps

The solution to the equation 0.6x - 5 = 0.1x + 7 is x = 24.

To solve the equation 0.6x - 5 = 0.1x + 7 for x, we need to isolate the variable x on one side of the equation. Here's the step-by-step explanation:

Step 1: Simplify the equation

Combine like terms on both sides of the equation.

0.6x - 0.1x - 5 = 0.1x - 0.1x + 7

0.5x - 5 = 7

Step 2: Move the constant term to the other side

To isolate the variable x, we want to get rid of the constant term on the same side as x.

0.5x - 5 + 5 = 7 + 5

0.5x = 12

Step 3: Solve for x

Now, we'll solve for x by dividing both sides of the equation by the coefficient of x, which is 0.5.

(0.5x)/0.5 = 12/0.5

x = 24

So the solution to the equation 0.6x - 5 = 0.1x + 7 is x = 24.

Find two numbers whose LCM is 90

Answers

To find the LCM for 90 since it has a zero, the first LCM is going to be 10. And 10 multiplied by 9 is 90. You can also divide the 90 by 5 and get 18.
One way working this out is to find all the numbers that go into 90 by listing all the pairs of numbers that multiply to give 90

1 × 90
2 × 45
3 × 30
6 × 15
9 × 10

From here we can do trial and error:

Let's choose any two factors, say 2 and 3
By listing their multiples, we will find their LCM is 6, not 90

Then choose any two factors, say 3 and 6
By listing their multiples, we will find their LCM is 6, not 90

We can try some bigger number, say 45 and 90
by listing their multiples, we will find their LCM 90

588 = 3n Please help I don't understand this!

Answers

Simplifying
588 = 3n

Solving
588 = 3n

Solving for variable 'n'.

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

Add '-3n' to each side of the equation.
588 + -3n = 3n + -3n

Combine like terms: 3n + -3n = 0
588 + -3n = 0

Add '-588' to each side of the equation.
588 + -588 + -3n = 0 + -588

Combine like terms: 588 + -588 = 0
0 + -3n = 0 + -588
-3n = 0 + -588

Combine like terms: 0 + -588 = -588
-3n = -588

Divide each side by '-3'.
n = 196

Simplifying
n = 196
Hello!

First, let's write the problem,
[tex]588 = 3n[/tex]
Let's switch sides now, otherwise, we are going to end up doing it later.
[tex]3n=588[/tex]
Divide both sides by 3.
[tex]\frac{3n}{3}=\frac{588}{3}[/tex]
Simplify.
[tex]n=196[/tex]
That would be our final answer.

If a square with a side of six is cut into three congruent rectangles, what is the perimeter of one of those rectangles

Answers

16 should be the correct answer
First of all, it is hard to know how to do this problem if you do not understand all the terms being used.

Square= a shape with four sides of equal length that meet to form four right angles.
Congruent rectangles = rectangles that are exactly the same in size and shape.
Perimeter = in this case, it is the sum of all the sides of the rectangle

The question asks you to divide a square with sides that are 6 units long into 3 congruent rectangles. 
If it is hard to picture this in your head, I recommend that you draw a picture. I drew one for you so you can see how mine looks. In the picture, you can see I cut one side of the square into 3 equal pieces. So, we divide the total side length by the number of equal divisions to get the heights of the rectangles. I got height (h)= 2 units. To find the width of the rectangles, you can merely use the length of a side of the square. So, the width(w)=6 units. So, then to get the perimeter of a rectangle you add up all the sides. Perimeter= h+h+w+w= 2+2+6+6= 16 units. I got rectangle perimeter=16 units for my final answer. Hope this helped! Comment on this answer if you still have any questions or you think I messed up. :)
