What is an linear equation in math?
A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included.
The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."
The two numbers are 15.75 and 176.3
First we will compare the numbers.
1. A=176.3
2. B=15.75
one's place of A is greater than once place of B.
tens place of A is greater than tens place of B.
Hundred place of A is greater than hundred place of B.
So, A>B
So we will subtract 15.75 from 176.3.
176.30 -15.75=
176.30 ----A
- 1 5.75 ----B
Hundreths place of A - Hundreths place of B = 0-5=10-5=5
Tenth place of A - Tenth place of B =12-7=5
ones place of A - ones place of B=5-5=0
Tens place of A - Tens place of B =7-1=6
So the solution is 160.55

176.912 round off to the closest integer.
Answer:
177
Step-by-step explanation:
An integer is a negative or positive whole number. any number greater or equal to 5 you round up the the nearest whole number
Hope this helps.
"decimals are not included in the set of integers." with this information you can infer that you need to round to the nearest whole number, therefore 176.912 would be round to 177 because the decimal in the tenth place is 5 or above (9) so you round UP.
Q.4 - Simplify: 7y + 8 = 9 + 3y + 2y. Show your work.
Answer:
y = 1/2
Step-by-step explanation:
7y + 8 = 9 + 3y + 2y
7y + 8 = 9 + 5y
7y - 5y + 8 = 9 + 5y - 5y (subtract 5y from both sides)
2y + 8 - 8 = 9 - 8 ( subtract 8 from both sides)
2y = 1
(2/2)y = (1/2) divide by 2 on both sides
y = 1/2

What is meant by scientific notation?Scientific notation is a method of expressing numbers that are either too large or too small to be written in decimal form. In the United Kingdom, it is known as scientific form, standard index form, or standard form.
The proper scientific notation format is [tex]a*10^b[/tex], where an is a number or decimal number with an absolute value greater than or equal to one and less than ten, or 1 |a| 10. b is the power of ten required for scientific notation to be mathematically equivalent to the original number.
In the scientific notation, the number is written as a multiplication of a number from 1 to 9 and 10 raised to the adequate power.
602,200,000,000,000,000,000,000
= 6.202 [tex]*[/tex] 100,000,000,000,000,000,000,000.
Since 10 = [tex]10^1[/tex]; 100 = [tex]$$10^2[/tex]; 1,000 = [tex]$$10^3[/tex], etc. then
100,000,000,000,000,000,000,000 = [tex]$$10^{23[/tex].
602,200,000,000,000,000,000,000
= 6.202 [tex]*[/tex] 100,000,000,000,000,000,000,000 = 6.022 [tex]*[/tex] [tex]$$10^{23[/tex].
The correct way to write 602,200,000,000,000,000,000,000 in scientific notation is 6.022 [tex]*[/tex] [tex]$$10^{23[/tex].
Therefore, the correct answer is option d) 6.022 [tex]*[/tex] [tex]$$10^{23[/tex].
The complete question is:

Johnny wants to buy a box of
donuts. The donuts normally cost
$12 dollars but they are on sale for
10% off. What is the sale price for
the donuts? Please I need help
Answer:
$1.20
Step-by-step explanation:
if the donuts normally cost 12 dollars, but they are on on sale for 10% off, then all you have to do is divide 12 by 10.
12 ÷ 10 = 1.2
since we are working with money, we need to add a 0 at the end to make it 1.20, since you need 100 cents to make a dollar.
another way you could write the equation is,
10% × 12 = 1.2
1.2 = 1.20
hence, the sale price for the donuts is $1.20
Step-by-step explanation:
Hope it helps!

) You are deciding between two landscaping companies to work on your backyard renovation. Company A charges a $50 fee to come out to your house plus $10 an hour to work. Company B charges $15 per hour and $30 to show up. How many hours will it take for both companies to equal the same price, and how much money will it cost at that time?
Considering the definition of an equation and the way to solve it, it will take 4 hours for both companies to equal the same price and it will cost $90 at that time.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.
The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:
When a value that is adding, when passing to the other member of the equation, it will subtract.If a value you are subtracting goes to the other side of the equation by adding.When a value you are dividing goes to another side of the equation, it will multiply whatever is on the other side.If a value is multiplying it passes to the other side of the equation, it will pass by dividing everything on the other side.This caseFirst, you define the variable "t" as the time for the landscaping company to work on the backyard renovation. You know that:
Company A charges a $50 fee to come out to your house plus $10 an hour to work. Company B charges $15 per hour and $30 to show up.So the price of each company is:
Price of company A=50 + 10tPrice of company B=30 + 15tIf both companies equal the same price, the equation in this case is:
Price of company A= Price of company B
50+ 10t= 30 + 15t
Solving
50 - 30= 15t - 10t
20= 5t
20÷5= t
4=t
At this time, the price of both companies is
Price of company A= 50+ 10t= 50 + 10×4= 90Price of company B= 30 + 15t= 30 + 15×4= 90In summary, it will take 4 hours for both companies to equal the same price and it will cost $90 at that time.

What does "compounding" mean?When interest is applied to a principal amount together with the interest that has already been paid, this process is known as compounding. This means that compounding, sometimes known as the "wonder of compounding," can be thought of as interest on the compound, which has the effect of increasing returns from interest over time.
What is an appropriate compounding procedure?Current good compounding practices refer to the minimal requirements for the procedures, facilities, and controls used to compound medicine to ensure that it has the identity, and strength, and satisfies the quality and purity requirements it is claimed to have.
According to the given information:She puts in one penny the first day, 2 pennies the second, 4 pennies the third...and so on.
The total sum is thus,
(1, 3, 7, 15, 31, 63, 127)
Which translate to
(2^1-1, 2^2-1, 2^3-1, 2^4-1, 2^5-1, 2^6-1, 2^7-1,..)
So at the end of the 75th day, the total amount is 2^75-1
or
37778931862957161709567 pennies
or
377,789,318,629,571,617,095.67 dollars.

Sharon is twice as old as Brain. In 5 years, the sum of their ages will be 25 years. Find their present ages.
Please Mark as Brainliest
Answer:
Brian is 5, and Sharon is 10
Step-by-step explanation:
CURRENT AGES:
Let b = Brian's age
Let 2b = Sharon's age
5 YEARS FROM NOW:
b + 5 = Brian's age
2b + 5 = Sharon's age
The sum will be 25
b + 5 + 2b + 5 = 25
3b + 10 = 25
3b = 15
b = 5
So Brian is 5, and Sharon is 10
