Answer:

n= 42

Step-by-step explanation:

Given expression is: 3(n-5)-2(n+8)=11  

Now, first of all we will multiply the numbers which are outside the brackets to the numbers inside. Which will become:  

3n-15 - 2n - 16 = 11

Next the second step is to the change the positions. The numbers that are multiplied by n will be together:  

3n - 2n -15 - 16 = 11

Finally, by solving the above equation. We get:

n - 31= 11

n = 11+ 31  

n= 42

Required answer is n = 42

Answer:

n=42

Step-by-step explanation:

The first step is to open the brackets by multiplying the vale before the brackets to the values inside the brackets giving attention to the signs which gives:

3n-15-2n-16=11

Then we collect like terms together.

3n-2n-15-16=11

evaluating the above equation we get

n-31=11

n=11+31

=42

The slope of the line below is 2 use the coordinates of the labeled point to find a point slope equation of the line
yan [13]

Answer:

B.

Step-by-step explanation:

The answer is B. The problem says that the slope is 2 and it as the points (3,10) on its line. When looking at the graph, you can see that the line crosses at four on the y-intercept which is why four will be your constant. So, your equation in slope intercept form will become y=2x+4. With this, you can start eliminating the given answers.

You can immediately eliminate c and d because the 2 is negative when it isn't in its slope form. It leaves you with a and b.

When looking at both a and b you now have to look at what your y will become when you sinplify both of them. In choice a, the 2 multiplies with the 3 and gives you 6. Since you have to leave the y by itself you have to subtract 10 from both sides which will leave you with -4. Since your y-intercept isn't negative you know that a isnt the ansewr.

When checking b, you multiply the 2 and -3 to get -6. Since you have to leave the y by itself, you add 10 to each side and end up with 4 which is the same number that crosses the y-axis. and that is how you know it's the right answer.

0.4 in fraction form. Please
Digiron [165]

Answer:

4/10

Step-by-step explanation:

0.4 is said by "four-tenths." Fractions are also said the same way. Notice how there is a four and a ten. This should be easier to help you make decimals in fraction form. The four would be the numerator and the ten would be the denominator, making the final answer 4/10.

In 2010, the population of a city was 161,000. From 2010 to 2015, the population grew by 8%. From 2015 to 2020, it fell by 6.7%.
solniwko [45]

Answer:

99%

Step-by-step explanation:

2010 population = 161,000

From 2010 to 2015, the population grew by 8%.

2010 to 2015 = 161,000 + (8% of 161,000)

= 161,000 + (0.08 * 161,000)

= 161,000 + 12,880

= 173,880

2010 to 2015 = 173,880

From 2015 to 2020, it fell by 6.7%

2015 to 2020 = 173,880 - (6.7% of 173,880)

= 173,880 - (0.067 * 173,880)

= 173,880 - 11,649.96

= 162,230.04

2015 to 2020 = 162,230.04

what percent did the city grow from 2010 to 2020.

= 161,000 / 162,230.04 × 100

= 0.9924179270374 × 100

= 99.241792703743

Approximately, 99% to the nearest whole number
