What is the value of n when 7n – 18 = 5n + 6?

Mathematics

forsale [732]3 years ago

Answer:

n=13

Step-by-step explanation:

7n-18=5n+6   move variables to 1 side

-5           -5    (in this case subtract 5 on both sides of the equal sign)

2n-18=  6        now you want to get the variable alone

   +18   +18     (in this case add 18 on both sides of the equal sign)

2n=26             now you want to get the variable (N) by itself

/2    /2            ( so divide 2 on both sides of the equal sign )

n=13

Answer:

n=12

Step-by-step explanation:

7n-18 =5n+6

+18 to both sides

7n=5n+24

-5n from both sides

2n=24

divide by 2

n=12

<span>The first and last four numbers each have a difference of one between them. The fifth number has a difference of 10 between it and the previous number. The middle number has a difference of 20 between itself and the two numbers that surround it. Counting in this way could have been a result of a lot of things to count, and spot checking along the way (when the numbers have a difference of 1).</span>

A stadium brings in $16.25 million per year. it pays football-related expenses of $13.5 million and stadium expenses of $2.7 mil
Ganezh [65]
We have that

Profit margin is calculated by finding the net profit as a percentage of the revenue

Profit margin = [Net profit / Revenue]

Net profit= [Revenue-Cost]

we know that

Revenue = $16.25 million

Cost = $13.5 million + $2.7 million

Net profit = [16.25 million - (13.5 million + 2.7 million)]

Net profit = $0.05 million

Profit margin = 0.05 / 16.25

Profit margin = 0.003077 or 0.3077%

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?
pshichka [43]
THE SLOPE IS -2



if we have the coordinates of two points on a line, we can find the slope with this formula:
s =  \frac{y2 - y1}{x2 -x1}  =  \frac{y1 - y2}{x1 - x2}
so the slope is
\frac{8 - ( - 4)}{ - 1 - 5}  =  \frac{12}{ - 6}  =  - 2
the answer is -2



good luck
