Mean of total 5 digits is 18.6
Given:
Mean of first 3 digit = 19
Mean of next 2 digit = 18
Find:
Mean of total 5 digits
Computation:
Sum of first 3 digit = Mean of first 3 digit × Number of digits
Sum of first 3 digit = 19 × 3
Sum of first 3 digit = 57
Sum of next 2 digit = Mean of first 3 digit × Number of digits
Sum of next 2 digit = 18 × 2
Sum of next 2 digit = 36
Total of 5 digit = Sum of first 3 digit + Sum of next 2 digit
Total of 5 digit = 57 + 36
Total of 5 digit = 93
Mean of total 5 digits = Total of 5 digit / 5
Mean of total 5 digits = 93 / 5
Mean of total 5 digits = 18.6

The answer is "mean of all 5 digits is 18.6" and the further calculation can be defined as follows:
The mean would be the total number divided by the number of numbers. To obtain the mean, we add all the numbers and divide by number.It is also known as the "average" value, which was established by summing all data points then divided by the information gain amount.Its most popular statistics used to measure the center of a collection of data and analysis are the statistics sometimes referred to it as average by statistics.In this question, let the value are a,b,c..., and e So,Mean of 3 digits:
[tex]\to \bold{\frac{a+b+c}{3}}=19[/tex]
Mean of 2 digits:
[tex]\to \bold{\frac{d+e}{2}}=18[/tex]
Find:
Mean of all 5 digits =?
Calculating the sum of 3 digits:
[tex]\to \bold{\frac{a+b+c}{3}}=19\\\\\to \bold{a+b+c}=19 \times 3\\\\\to \bold{a+b+c}=57\\\\[/tex]
Calculating the sum of 2 digits:
[tex]\to \bold{\frac{d+e}{2}}=18\\\\\to \bold{d+e}=18\times 2\\\\\to \bold{d+e}=36\\\\[/tex]
Calculating the Mean of all 5 digits:
[tex]\to \bold{\frac{a+b+c+d+e}{5}}= \bold{\frac{57+36}{5}}[/tex]
[tex]= \bold{\frac{93}{5}}\\\\=\bold{18.6}[/tex]

What is Simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are all referred to as PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
Given, the values of a and b are 9/11 and 7/10 respectively
thus,
ab = 9/11 * 7/10
simplifying it
ab = 63/110
Therefore, the value of ab is 63/110 when a = 9/11 and b = 7/10

A number increased by 10 is 32. How would I write that as an equation?
Answer:
4.
Step-by-step explanation:
Remember that “of” means multiplication, so from your question we infer the following equation:
(1/2)x + 10 = 12
First, subtract 10 from both sides:
(1/2)x = 2
Multiply both sides by 2 to eliminate the fraction:
x = 4
Now substitute for x in the original equation to prove this:
(1/2)x + 10 = 12
x = 4
(1/2)4 + 10 = 12
4/2 + 10 = 12
2 + 10 = 12
12 = 12
So the number, x, is 4.

h=54+1/2at^2 solve for a
Im lost on if I should square the 1/2at first?
Other answer formats are possible.
===========================================================
Explanation:
Let's say we want to solve the equation h = 54 + 10a for the variable 'a'. This is relevant to the problem at hand don't worry.
What we'd do is two things
Subtract 54 from both sides Divide by 10So the steps look like this
h = 54 + 10a
h-54 = 10a
(h-54)/10 = a
a = (h-54)/10
Now let's say we wanted to solve this equation: h = 54 + ca, where c is a constant and can stand in place of any number. The steps would be pretty much identical. Instead of dividing both sides by 10, we divide both sides by c. We can do this as long as c isn't zero of course.
That means the equation h = 54+ca solves to a = (h-54)/c
---------------------------
Why did I do those examples? To build up to the equation your teacher gave you.
Let's replace c with 0.5t^2
This is because 1/2 = 0.5
The 1/2at^2 is the same as (1/2t^2)a
So instead of a = (h-54)/c, we'd get a = (h-54)/(0.5t^2)
As a last optional and encouraged step, we can multiply every term by 2 to get rid of that decimal value.
Doing so makes a = (h-54)/(0.5t^2) turn into a = (2h-108)/(t^2)
---------------------------
Here's another way to solve:
h = 54 + (1/2)at^2
h-54 = (1/2)at^2
2(h-54) = at^2
2h-108 = at^2
(2h-108)/(t^2) = a
a = (2h-108)/(t^2)
In the second step, I subtracted 54 from both sides. Immediately afterward, I multiplied both sides by 2 so I could clear out the fraction. Then I divided both sides by t^2 to fully isolated the variable 'a'.

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in "m" in different ways and if following it, a second event can occur in "n" ways; then the two events in succession can occur in m × n ways.
Given that Ryan has 21 pencils, wants to put the same number of pencils in each of the 3 pencil holders.
Pencil = 21
Pencil holder = 3
Therefore, we will do as 21 divided by 3
21/3 = 7
Hence, there are 7 pencils in each pencil holder.
