PLEASE I NEED HELP

Answer: 0.25 feet

Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips= $12x=3\ feet$

$\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet$

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.

So my math teacher doesn't give us any steps to know how to do the equations. She just tells us the unit, then the vocab plus th

Lemur [1.5K]

I personally understand what you are saying... everyone has a teacher like that at least once in their schooling.

Doing two-step equations can sometimes be tricky, even if you understand the topic pretty well. All two-step equations are: equations that require two objectives to solve for the variable (That's why it's called a <em>two-step </em>equation).

There are multi-step equations...but let's take one bite at a time.

First, let's establish one simple rule:

Anything you do to one side of the algebraic equation, you must do to the other side for the equation to remain true.

For example:

$2x-4=20$

So, we have this $2x-4$ just chillin' out with the $x$ . When trying to solve for a variable, this is usually not what we want. The $x$ needs to be alone for us to know what $x$ equals.

For the first step of getting $x$ alone, we can add $4$ on each side of the equation to cancel out the $-4$ on the variable's side. Remember to do it on both sides of the equation!

$2x-4=20$ becomes $2x-4+4=20+4$

Did you see what I did there? All I did was basically add $4$ to $2x-4$ and $20$ . The equation remains equal, but using that simple rule, we were able to get one step closer to isolating the $x$ in the equation.

To continue...

$2x-4+4=20+4$

$2x-4+4$ turns into $2x$ <em>(This is because the $-4$ and the $+4$ cancel out.)</em>

Now we have $2x=24$

This next step should look familiar to you (assuming you already know how to solve for one-step equations, I'll keep it short and sweet).

$2x=24$

Now, since $2x$ is the same as saying $2$ times $x$ , we can do the opposite of multiplication...which is <em>division, </em>like so:

$\frac{2x}{2} =\frac{24}{2}$

The $2$ 's will cancel each other out and $\frac{24}{2}$ simplifies to $12$ .

Awesome! Looks like we solved our two-step equation!

In the equation: $2x-4=20$ , $x=12$

Some things to remember:

What ever you do to one side of the equation, you must do to the other.
You want to apply the opposite sign of the number you are trying to cancel out of the equation while isolating the $x$ .
Never make it harder than it needs to be. It is called a two-step equation for a reason, multi-step requires more than two...but wait until you have to work those before you start using fifty different ways to solve the equation.

Hope I was able to help you out! Have a good one, and God bless!

One side of a right triangle has a length of 24 centimeters. What could be the lengths of the other two sides of the right trian

Zanzabum

Answer:

A. 7 centimetres and 25 centimetres

Step-by-step explanation:

To see if the lengths make a triangle, use the Pythagorean theorem. Insert the biggest value as c (the hypotenuse, which is always the longest side in a right triangle). If both sides equal each other, it is a right triangle:

$a^2+b^2=c^2$

A.

$24^2+7^2=25^2\\\\576+49=625\\\\625=625$

This is a right triangle.

B.

$23^2+8^2=24^2\\\\529+64=576\\\\593\neq 576$

Not a right triangle.

C.

$9^2+22^2=24^2\\\\81+484=576\\\\565\neq 576$

Not a right triangle.

D.

$24^2+10^2=27^2\\\\576+100=729\\\\676\neq 729$

Not a right triangle.

Done :D
