4x+1+3=8 ayuden manden paso a paso
Answer:
x = 1
Step-by-step explanation:
Solve for x:
4 x + 1 + 3 = 8
Hint: | Group like terms in 4 x + 1 + 3.
Grouping like terms, 4 x + 1 + 3 = 4 x + (1 + 3):
4 x + (1 + 3) = 8
Hint: | Evaluate 1 + 3.
1 + 3 = 4:
4 x + 4 = 8
Hint: | Isolate terms with x to the left hand side.
Subtract 4 from both sides:
4 x + (4 - 4) = 8 - 4
Hint: | Look for the difference of two identical terms.
4 - 4 = 0:
4 x = 8 - 4
Hint: | Evaluate 8 - 4.
8 - 4 = 4:
4 x = 4
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 4 x = 4 by 4:
(4 x)/4 = 4/4
Hint: | Any nonzero number divided by itself is one.
4/4 = 1:
x = 4/4
Hint: | Any nonzero number divided by itself is one.

The profit a company urns every month depends on the amount of product sold, p, for $855 each and the amount spent in rent, utilities and other expenses, which always totals to $6,780. The CEO of the company earns 15% of this profit. How much does the CO heard if the company sells 250 products in a given month?
Answer:
CEO earns $31,045.5
Step-by-step explanation:
Price of each product = $855
Number of product sold = 250
Total revenue = price × quantity
= 855 × 250
= $213,750
Total expenditure = $6,780
Profits = Total revenue - Total expenditure
= 213,750 - 6,780
= $206,970
Profits = $206,970
The CEO of the company earns 15% of this profit
Amount CEO earns = 15% of $206,970
= 15/100 × 206,970
= 0.15 × 206,970
= $31,045.5
CEO earns $31,045.5

Which statement or statements accurately describe a good way to avoid excessive service fees? I. Try to deposit money in large batches rather than in small amounts. II. Try to limit the number of withdrawals you make from out-of-network ATMs. III. Try to avoid using your debit card online. a. I and II b. II only c. III only d. I and III
Answer:
Option B: II only
Step-by-step explanation:
Looking at the statements;
In statement I, whether making big at once or small deposits periodically, they have no impact in terms of charges from banks because banks don't charge any excessive fee for direct deposits.
In statement II, using out of network ATM would mean more excessive service fees. This is because your host bank which issued you the ATM card will charge you for using a non - network machine. In addition to that, the ATM operator where you are withdrawing from will also charge you a fee. This is double charge from 2 streams thus avoiding it will mean no excessive charges.
In statement III, some banks may or may not issue some fee for making online transactions with debit card depending on what exactly you want to do. However, it's just a small fee and thus, using it doesn't cause excessive charges.
Thus, the one to avoid will be statement II.

what is the slope of the line that passes through the points (-6,-7) and (-24,-7)? Write your answer in the simplest form.
Answer:
The slope calculator determines the slope or gradient between two points in the Cartesian coordinate system. The slope is basically the amount of slant a line has, and can have a positive, negative, zero or undefined value. Before we can use the calculator it is probably worth learning how to find the slope using the slope formula. To find the equation of a line for any given two points that this line passes through, use our slope intercept form calculator.
How to find slope
Identify the coordinates (x₁,y₁)and(x₂,y₂). We will use the formula to calculate the slope of the line passing through the points (3,8) and (-2, 10).
Input the values into the formula. This gives us (10 - 8)/(-2 - 3).
Subtract the values in parentheses to get 2/(-5).
Simplify the fraction to get the slope of -2/5.
Check your result using the slope calculator.
To find the slope of a line we need two coordinates on the line. Any two coordinates will suffice. We are basically measuring the amount of change of the y-coordinate, often known as the rise, divided by the change of the x-coordinate, known the the run. The calculations in finding the slope are simple and involves nothing more than basic subtraction and division.
The slope formula
slope = (y₂ - y₁) / (x₂ - x₁)
Notice that the slope of a line is easily calculated by hand using small, whole number coordinates. The formula becomes increasingly useful as the coordinates take on larger values or decimal values.
It is worth mentioning that any horizontal line has a gradient of zero because a horizontal line has the same y-coordinates. This will result in a zero in the numerator of the slope formula. On the other hand, a vertical line will have an undefined slope since the x-coordinates will always be the same. This will result the division by zero error when using the formula.
Other related topics
Just as slope can be calculated using the endpoints of a segment, the midpoint can also be calculated. The midpoint is an important concept in geometry, particularly when inscribing a polygon inside another polygon with the its vertices touching the midpoint of the sides of the larger polygon. This can be obtained using the midpoint calculator or by simply taking the average of each x-coordinates and the average of the y-coordinates to form a new coordinate.

At an opening of a new art gallery, the owner hired a caterer to serve light snacks. The owner created a budget for 150 people to attend the opening, with a per person food cost of $4.25. If the number of guests attending the opening was 56% more than expected, then how much was the final food cost?
Answer:
$994.5
Step-by-step explanation:
At an opening of a new art gallery, the owner hired a caterer to serve light snacks. The owner created a budget for 150 people to attend the opening, with a per person food cost of $4.25.
Cost for 150 persons =
150 × $4.25 = $637.5
If the number of guests attending the opening was 56% more than expected, then how much was the final food cost?
Percentage increase = Final value - Initial value /Initial value
56% = x - 150/150
Cross Multiply
0.56 × 150 = x - 150
84 = x - 150
x = 150 + 84
x= 234 people
56% increase means 84 extra people came
Total people that came = 234 people
From the question, we know that: per person food cost of $4.25.
Hence
1 person = $4.25
234 persons =
234 × $4.25
= $994.5
Therefore, the final food cost is $994.5

It takes the earth 24 h to complete a full rotation. It takes Mercury approximately 58 days, 15 h, and 30 min to complete a full rotation. How many hours does it take Mercury to complete a full rotation? Show your work using the correct conversion factors.
Answer: 1407.5 hours
Step-by-step explanation:
Okay so looking at the problem, the conversion factors we are going to need are from days to hours and from minutes to hours. Let's start with the days to hours first. If there are 24 hours in a day and we have 58 days then 24x58 would get us the hours that we need. So we would get 1392 hours. Add that to the hours already present and you get 1407 hours and 30 minutes. Since 30 minutes is half of one hour you can either use a fraction or decimal to give your answer: 1407.5 hours or hours
