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
The way that you would do this is by taking

out of the binomial, or as I like to think about it, 'un-distributing'. :p

out of

, you end up with

.
When you take

out of

, you get

.
Put it together, and the solution is

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:

Now, we solve this by cross multiplying.
150x = 100
Dividing both sides by x, we get x = 2/3 or about 0.667.

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.
