What is rounding off number?Rounding is a technique to reduce a large number to a smaller, more approachable figure which is very similar to the actual. Rounding numbers can be achieved in a variety of ways.
We have a number:
= 3.84761
It is required to round off to 3 decimal place.
= 3.848 (0.0076 = 0.008)
Rounded to the nearest 0.001 or the Thousandths Place.

Solve the system of equations -x + 2y = –2 and 6x – y = -43 by combining
the equations.
Answer:
{x,y}={-8,-5}
Step-by-step explanation:
/ Solve equation [2] for the variable y
[2] y = 6x + 43
// Plug this in for variable y in equation [1]
[1] -x + 2•(6x+43) = -2
[1] 11x = -88
// Solve equation [1] for the variable x
[1] 11x = - 88
[1] x = - 8
// By now we know this much :
x = -8
y = 6x+43
// Use the x value to solve for y
y = 6(-8)+43 = -5
Solution :
{x,y} = {-8,-5}

Answer:
10.) If you buy all larger cans (aka the 7-gallon cans), you would have saved approx. $30.21
9.) Seth would need a score of 95% in order to average an 80%
Step-by-step explanation:
10.) It costs $15.50 per 5-gal. If you want to buy 45 gallons, it would cost you $139.50 if you bought 5-gallon cans.
It costs $17.00 per 7-gallon. If you want to buy 45 gallons, it would cost you $109.29 if you bought 7-gallon cans.
Now, let's compare prices. Buying 45 gallons worth of 7-gallon cans is less expensive by.... (139.50 - 109.29 = 30.21)
Therefore, you saved $30.21.
9.) An average is done by adding up all the numbers and dividing it by how many numbers you added it by. Let's write an equation to make things easier. So far, we don't know the score he needs to get on his fourth test so let's make it a variable x.
(82 + 68 + 75 + x) / 4 = 80
Let's solve for x.
(82 + 68 + 75 + x) / 4 = 80 *Multiply both sides by 4
82 + 68 + 75 + x = 320 *Add like terms
225 + x = 320 *Subtract 225 from boths to get x on one side
x = 95

There are four students working on a project in math class. Miguel has completed 1/8 of the project, Gina has completed 13% of the project, Jatziry has completed 0. 10 of the project, and Kwa has completed 1/9 of the project. Make a list of the students in order from least to greatest by the amount of the project they have completed.
There are a few methods to doing this, but lets make every number a fraction. (You could make them all percentages or decimals if you want, but it is more difficult in my opinion.)
Miguel: 1/8
Gina: 13/100
Jatziry: 10/100 = 1/10
Kwa: 1/9
Now we need to find the least common denominator, which is 1800.
Now you have these fractions:
Miguel: 225/1800
Gina: 234/1800
Jatziry: 180/1800
Kwa: 200/1800
Now you can easily list these in order
180/1800 < 200/1800 < 234/1800 < 225/1800
Jatziry < Kwa < Gina < Miguel
Sorry if I made any mistakes, I realized Jatziry was a part of the problem halfway through.
In an earlier lesson, we saw this graph that shows the percentage of all garbage in the U.S. that was recycled between 1991 and 2013.
1) Sketch a linear function that models the change in the percentage of garbage that was recycled between 1991 and 1995. For which years is the model good at predicting the percentage of garbage that is produced? For which years is it not as good?
2) Pick another time period to model with a sketch of a linear function. For which years is the model good at making predictions? For which years is it not very good?
Answer:
here we can use mathematics to make an equation but according to the questions rewarded marks we can only determine an sketch of best fit line
and not good in 1993 (predicted as graph is less accurate)
other period is 1995 to 2005

First, convert these two mixed fractions into improper fractions.
You can do that by following these steps:
Multiply the outside number by the number in the denominator
Add the product to the number in the numerator
5[tex]\frac{1}{4}[/tex] = [tex]\frac{21}{4}[/tex]
3[tex]\frac{7}{8}[/tex] = [tex]\frac{31}{8}[/tex]
Now, convert these fractions so that they share the same denominator. 4 and 8 share the same factor of 8. Multiply the numerator and denominator of [tex]\frac{21}{4}[/tex] by 2 so that the denominator becomes 8.
[tex]\frac{21}{4}[/tex] = [tex]\frac{42}{8}[/tex]
Now find how many inches of string each person has by using multiplication:
Sophie has [tex]\frac{42}{8}[/tex] × 5 = [tex]\frac{210}{8}[/tex] inches total
Cooper has [tex]\frac{31}{8}[/tex] × 4 = [tex]\frac{124}{8}[/tex] inches total
To find how much more inches Sophie has, subtract the two fraction from each other:
[tex]\frac{210}{8} - \frac{124}{8}[/tex] = [tex]\frac{86}{8}[/tex]
Simplify the fraction:
Sophie has 10[tex]\frac{6}{8}[/tex] or 10[tex]\frac{3}{4}[/tex] more inches than Cooper

True:
The solution is the product of two factors.
The second factor is itself the sum of three terms.
False:
The solution is the sum of two terms.
The coefficient is 3. (This one I'm confused about. There is no x/letter term, so there shouldn't be a coefficient in this problem at all.)
