1:x = X:64. What One Number Can Replace X
Introduction
In this article today, we'll be going over a maths sum. There will be two types of people reading this, this first will be people who are studying maths, maybe even with an exam coming up. The other type will exist someone who wants to learn, or is merely bored and reading this because y'all have nothing better to practise.
No thing who you are, welcome! And I hope you lot can learn a thing or two.
1:ten = ten:64. What i number can supercede x?
If 1:x = 10:64, then x would have to be 8. It tin can be either positive 8 or negative 8. 8:64 = one:8 = 0.125 and -8:64 = 1:-8 = -0.125.
Today, I want to explain why it matters and how we get in that location.
Step Ane: 1:x = x:64. What one number tin can supplant x?
The first step is to figure out what the question is request. We need to simplify the problem to make information technology easier for united states of america to empathise what we're trying to do.
1:x = 10:64.
We're trying to figure out what number divided by 64 gives you the same respond if that number was divided by one.
one/viii is 0.125
viii/64 is 0.125
But at this stage, you won't take figured this out, unless you have a calculator, which y'all might not exist able to in an examination.
Step 2: All numbers on one side
Next upwards, nosotros'll demand to separate the numbers from the letters. We want the numbers on one side of the equals sign and the letters on the other.
Which one yous should bargain with first depends on what will be easier. This might vary depending on the sum.
In this case, it will be easier to get the numbers on the same side.
To do this, you should multiply both sides past 64.
i:x × 64 = 64:x. If you take one xth and it gets multiplied by 64, you'll 64 xths.
x:64 × 64 = x
Our new sum is now: 64:x= ten.
What number divided by 64 is itself?
Pace Three: All messages on one side
Now we've got all of the numbers on 1 side, the next step is going to be to get all of the letters onto the other side. The numbers are sorted, then the messages are the simply things that need shifting.
To do this, we'll need to multiply both sides by y.
64:x × ten = 64. If you take 64:x and multiply it by x, you'll get 64.
x×x= y2
At this bespeak, our new sum is 64= x2
Pace 4: What is √64?
We now need to find out what times itself is 64. Another mode nosotros could say this is "What squared is 64?" or "What is the square root of 64?".
If y'all're lucky, you lot can quickly figure this out by using a calculator. However, if you're reading this for grooming for an exam, you might non take a estimator in your exam hall when you're doing the exam.
If this is you, you'll need to know your square numbers or your 1-10 times table.
No matter what method you apply, √64= 8.
eight×8= 64.
Ratio
If you're not studying for an exam, some of you might be wondering what use ratio is going to be in the existent world. But actually, it'due south seen more ofttimes than you might think.
When painting, if you're mixing colours, you'll need to use ratio to know how much of each colour to add when y'all're mixing. Otherwise, the colour y'all'll get might not exist the colour you lot desire.
Y'all tin can also use information technology in politics. If someone says "I'm a supporter of Ten. I voted for it!". You could look at their voting record and say "Just for every time y'all've voted for X, you lot've voted confronting information technology 5 times".
And if you're cooking, y'all might get told, for every teaspoon of flour, use 3 splashes of milk. This is using ratio.
TL;DR version
i:x = 10:64
ane/ten= ten/64
×64
64/x= x
×ten
64= xtwo
√64= 10
√64= 8
x= eight
Why algebra is easy and how you tin can use it to solve i:ten = x:64
Many of us think of Algebra as being complicated and the sort of thing that you lot need to exist an expert in maths to understand.
A lot of this is likely because our maths teachers want us to find it complicated.
However, algebra doesn't need to be complicated. Here is an paradigm that you might have seen on social media.

We know that the apples are 10 because 3 of them are xxx.
Therefore two bananas are 8. Making one banana 4.
The coconut must be two because 4-2=two.
Coconut+Apple+Banana= 4+10+2= 16.
This might non seem like algebra because we're using fruit, not letters. But the rules and methods are the aforementioned, no matter what the symbols are.
What algebra is useful for
This, however, does beg the question of "What is the bespeak in using Algebra?". Apart from figuring out a fun Instagram post?
Let's say yous accept to put on a dinner for your family. And everyone should get 1 tin of beer. Y'all need to know how much this volition cost. C is the cost of 1 can of beer.
If you have four family unit members, the full price of beer will be 4C.
If y'all're a freelance writer, you might want to know if you're going to get paid enough. Allow'southward say someone wants 2500 words and will pay $20 for it. But you accuse $10 per chiliad words.
If $20= 2500 words
$x= 1250 words.
This is well within the amount you'll be willing to charge.
You might fifty-fifty driblet the price if you're feeling dainty.
What does "colon" hateful in algebra?
When nosotros're diving, in that location are a few symbols we can use. Usually, when writing on paper, we would write ÷. But when we're on a computer, we tend to write /.
Although ":" is used in ratio, to say 1:one (one to one ratio), is also to say ane divided by one.
So, ":" is some other symbol for division.
Decision
Even though many might think ratio and algebra stop beingness useful once we leave the maths classroom, the truth could not be further.
You never know when either of these skills might pop up in your working or personal life.
Hopefully, now, yous accept a slightly better idea of how to do these kinds of algebra sums.
