Khairul is x years old .Khairul`s uncle is 4 times as old as khairul will be in 5 years .Find the present age of Kharuls`s uncle
rodikova [14]

Answer:

4x + 15

Step-by-step explanation:

Let the age of Khairul's uncle y.

From the question given above, the following were obtained:

Khairul's age = x years

In 5 years time:

Khairul's age = x + 5

Khairul's uncle age = y + 5

But from the question given above,

Khairul`s uncle will be 4 times as old as what khairul will be in 5 years. This can be written as follow:

y + 5 = 4(x + 5)

Clear bracket

y + 5 = 4x + 20

Subtract 5 from both side

y + 5 – 5 = 4x + 20 – 5

y = 4x + 15

Therefore, Khairul's uncle present age is 4x + 15

Divide the binomial by the monomial to find the quotient -36x^4y + 144x^2 y^6/ -4x^2y
elixir [45]
The way that you would do this is by taking -4x^{2} out of the binomial, or as I like to think about it, 'un-distributing'. :p
-4x^{2} out of -36x^{2}y, you end up with 12x^{2}. 
When you take -4x^{2} out of 144x^{2}y{6}, you get -36y^{5}. 
Put it together, and the solution is 12x^{2} - 36y^{5}.

Hope I helped!!

Pls answer I really need help<br> Brainlist and thank you will be the reward thank you so much!!!
castortr0y [4]

Answer:

<h2>0.667 ✅</h2>

Step-by-step explanation:

This is best solved using a proportion.

The formula is soy/vinegar = soy/vinegar where one of these is a variable.

Here we have:

\frac{150}{100} = \frac{1}{x}

Now, we solve this by cross multiplying.

150x = 100

Dividing both sides by x, we get x = 2/3 or about 0.667.

Checking:

\frac{150}{100} = \frac{1}{0.667}

1.5 = 1.5 ✅

This dot plot is not symmetric, and the data set has two extreme values. What is the best measure of center for this dot plot?
Archy [21]

Answer:

The best measure of center for this dot plot is the median.

Choice A

Step-by-step explanation:

measures of center or location of a data set include;

the mean

the mode

the median

If a data set is symmetric or approximately normal then the best measure of center is the mean. On the other hand, for an asymmetric data with outliers the best measure of center is the median since it is robust to outliers.
