- 0.83 = -F
[?]
=
Hint: Subtract the first equation from this new
equation to eliminate the repeating decimal.
Enter the decimal value
the fraction form of the number will be 5 / 18.
We are given the decimal number as:
0.83(bar on 3) = F ...(1)
Now, we need to convert this into fraction.
For this, we will first multiply both the sides by 10
Do, we get that:
8.33 ( bar on 3) = 10 F ...(2)
Now, we will Subract (1) from (2), we get that:
9 F = 8.33 (bar on 3) - 0.83 (bar on 3)
9 F = 7.5
F = 7.5 / 9
F = 2.5 / 9
F = 25 / 90
Reducing the fraction into simplest form:
F = 5 / 18.
Therefore, we get that the fraction form of the number will be 5 / 18.

Answer:
Step-by-step explanation:
1) group any number with an X together and rewrite answer (if there is a negative in front of a number always carry it with it when rearranging.)
10x-10x-6-2
2) lets solve the numbers with Xs together
10x+10x= 20x
3) now lets solve whole numbers
-6-2=-8
4) bring down the 20x and the -8/ rewrite problem with your solved numbers
20x-8
5) we have to have X alone so in order to get rid of the 20 in front of the X you must divide 20 by 20x,
20x/20 ( it cancel's out and now you're left with X)
X=-8
6) but whatever you do to one side of the equal sign you have to do to the other side so now you must divide -8/20 which will leave you with

A school is organizing a weekend trip to a nature preserve. For each student, there is a $60 charge, which covers food and lodging. There is also a $40 charge per student for the bus. The school must also pay a $30 cleaning fee for the bus. If the total cost of the weekend is $4,030, how many students will be going on the trip?
31 students
40 students
41 students
66 students
Answer:
40 students
Step-by-step explanation:
I think it is 40 students because 60 + 40= 100 then 100 x 40 = 4,000
then the SCHOOL has to pay a $30 cleaning fee so that will add up to $4,030! I hope this helps everybody!
40 students will be going on the trip
How to calculate the number of students that will be going on the trip ?Each student will pay $60 for food and lodging
Each student will also pay $40 for the bus
Total amount of fee that will be paid by each student is
= 60 +40
= 100
The school will pay $30 cleaning fee for the bus, it's only the school that will be paying this fee, the students are not included. This will will be subtracted from the total cost which is $4,030 leaving us with $4,000
Therefore the number of students going on the trip can be calculated as follows
= 4,000/100
= 40
Hence 40 students will be going on the trip

Week Time (s)
28.8
27.6
27.1
How much greater was the percent of change from Week 1 to Week 2 than from Week 2 to Week 3? Round to the nearest tenth of a percent
Randy's percentage change from Week 1 to Week 2 was 2.37% greater than Week 2 to Week 3.
The percentage change will be calculated by the relation -
Percentage change = change in timing ÷ original time × 100
Calculating percentage change between Week 1 and Week 2
Change = 28.8 - 27.6
Change = 1.2 seconds
Percentage = (1.2 ÷ 28.8) × 100
Percentage = 4.17%
Calculating percentage change between Week 2 and Week 3
Change = 27.6 - 27.1
Change = 0.5 seconds
Percentage = (0.5 ÷ 27.6) × 100
Percentage = 1.8%
So, percent of change from Week 1 to Week 2 than from Week 2 to Week 3 was = 4.17 - 1.8
Percentage change = 2.37%
Therefore, the percentage change from Week 1 to Week 2 was 2.37% greater than Week 2 to Week 3.

This part of the wall is 5 metres long and 1.5 metres high.
The complete wall will be 8 metres long and 1.5 metres high.
How many more bricks does Jack need to complete the wall?
The amount of bricks that Jack would need to complete the wall is 180.
How many more bricks does he need?The first step is to determine the total amount of bricks he would need to build the wall. In order to determine this value, ratio analysis would be used.
Total bricks needed = (area of wall x number of blocks already used) / (area of wall already built)
Area of wall = 8 x 1.5 = 12
Area of wall already built = 5 x 1.5 = 7.5
Total bricks needed = (12 x 300) / 7.5 = 400 bricks
Number of bricks needed to complete the wall = 400 - 300 = 180 bricks

If the difference of a number and eight is tripled and the result is six more than the number, the number is 15
How to find the number using variable?The difference of a number and eight is tripled, then the result is six more than the number.
Therefore, the number will be represented by a variable
let the number = x
Hence,
3(x - 8) = x + 6
Therefore, let's open the bracket
3(x - 8) = x + 6
3x - 24 = x + 6
subtract x from both sides of the equation

He wouldn’t be able to meet the specifications as the heigh is greater than the maximum height.
In mathematics, the greater than sign is a basic mathematical notation used to represent an inequality between two values. The symbol used to denote greater inequality is “>”. It is the commonly accepted mathematical notation of two strokes of equal length that meet at an acute right angle. A typical use of the greater than sign is to compare two values, where the first is greater than the second, or one is greater than the other. The greater than sign is an approximation of a closing square bracket.Maximum width of the wall hanging can be 3.75 feet and maximum height can be 6.5 feet.
After completing the work it was found that the width measures 3 3/5 feet and height was 3 3/4 tall.

|x-2|=|4+x|
How can I find the value of X?
Answer:
x = -1
Step-by-step explanation:
You want to find the value(s) of x that satisfy the equation |x-2| = |4+x|.
DomainsThe behavior of each absolute value function changes at the point where its argument is zero. For this equation, that will be two points:
x -2 = 0 ⇒ x = 2
x +4 = 0 ⇒ x = -4
These two points on the number line divide the domain of the equation into three parts:
x < -4-4 ≤ x < 22 ≤ x.The behavior of the equation will be different in those three domains.
x < -4In this domain, both absolute value functions negate their arguments. That means the equation is equivalent to ...
-(x -2) = -(4 +x)
2 = -4 . . . . . . . . . . add x to both sides
This has no solutions: there are no values of x that will make this true.
-4 ≤ x < 2In this domain, the absolute value function on the left negates its argument, so the equation is equivalent to ...
-(x -2) = (4 +x)
-2 = 2x . . . . . . . . . add x-4 to both sides
-1 = x . . . . . . . . . divide by 2
This value of x is in the domain, so represents a solution to the equation.
x = -1
2 ≤ xIn this domain, neither absolute value function negates its argument, so the equation is equivalent to ...
x -2 = 4 +x
-2 = 4 . . . . . . . subtract x
This has no solutions: there are no values of x that will make this true.
The given equation has one solution: x = -1.
__
Additional comment
When solving an equation like this graphically, it is often useful to put it in the form f(x) = 0. We can obtain that form by defining ...
f(x) = |x -2| -|4 +x|
The graph of this is attached. The only solution is where f(x) = 0, at x = -1.
Note that the function is parallel to the x-axis outside of the middle domain, so will not have any x-intercepts in those regions.

consecutive integers whose sum is 67. Find these page
numbers. Show your work (the steps)! Show the original
equation. Write a short summary of the result. Hint: Let x be the
first consecutive integer.
The original equation will be x + x + 1 = 67 and the left page will have 33 page number and the right one will have 34 page number.
Let x be the first consecutive integer.
So, x + 1 is the first consecutive integer.
Sum of the two integers = 67
⇒ x + x + 1 = 67 (This is the original equation)
Combining the like terms:
⇒ 2x + 1 = 67
Subtract 1 from both the sides:
⇒ 2x = 67 - 1
⇒ 2x = 66
Divide both sides by 2:
⇒ x = 66/2 = 33
Therefore, the original equation will be x + x + 1 = 67 and the left page will have 33 page number and the right one will have 34 page number.

Step-by-step explanation:
Irrational numbers are those which cannot be expressed by the ratio of two integers.
A is rational because it is a recurring decimal. Recurring decimals can be represented by the ratio of two integers (this one can be represented by the fraction -2752/333, which is a ratio of two integers).
B is a fraction with two integers, therefore it is rational. -5/9 is a ratio of two integers.
C can be represented by 1747/100.
D is an infinite decimal but isn't recurring like A, meaning it cannot be represented by the ratio of two integers, and is therefore it is irrational, unless you are shown further digits of the decimal which prove it to be recurring, which is not the case here.
