Answer:
n>5
Step-by-step explanation:
move the 20 onto the other side of the > by subtracting 20 on the left side and adding 20 on the right side
now you have
-3n>7n-20
move the 7n onto the other side the same way. subtract 7n from one side and add it to -3n. now you have
4n>20
this is called adding similar terms or inverse operations what ever you wanna call it. Now you divide N by 4. This is because 4n can be simplified to 4×N and the opposite of multiplication is division. you do the same on the other side.
n/4>20/4.
you are left with n>5
Answer:
n<2
Step-by-step explanation:
Subtract 20 from both sides 20-3n-20>7n-20
Simplify -3n>7n-20
Subtract 7n from both sides -3n-7n>7n-20-7n
Simplify again -10n>-20
multiply both sides by -1 (-10n)(-1) < (-20)(-1)
Simplify 10n<20
Divide both sides by 10 Then you get your answer

The local high school sold 1914 tickets this year to its spring musical. That was 174 more tickets sold than last year. What is the percent increase in the number of tickets sold?
Answer:
.909 (ROUNDED)
Step-by-step explanation:
In order to do this all you need to do is divide the number with the number you got this year, 1914, and with the number last year.
1914-174=1740
1740 was the amount they got last year
Now you want to find the percent difference between the two.
1740/1914=.909090 (Repeats)
So the percent increase would be
.909090
.101010

what is the equation
Answer:
y = -2/5x + 9
Step-by-step explanation:
The slope will always be before the x. And intercept will always go after the slope. If your intercept is negative, remember to write it as x-9 rather than x+9.
And you'll always want to add the y = at the beginning

On the first night, the Movie House Theater sold 7 adult tickets and 11 child tickets for
$227. On the second night they took in $150 by selling 6 adult tickets and 6 child tickets.
Find the price of an adult ticket and the price of a child ticket.
Answer:
Adults $10
Child: $6
Step-by-step explanation:
I took the test
The price of an adult ticket and the price of a child ticket are $12 and $13.
What is the system of equation?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
On the first night,
the Movie House Theater sold 7 adult tickets and 11 child tickets for $227.
On the second night, they took in $150 by selling 6 adult tickets and 6 child tickets.
Let x be the number of tickets sold to an adult and y be the number of tickets sold to a child.
According to the question,
7x + 11y = 227 equation 1
and 6x + 6y = 150,
Simplifying,
x + y = 25 equation 2
Now, we have a system of equations.
7x + 11y = 227 equation 1
x + y = 25 equation 2
From the equation 2 we have,
y = 25 - x
Substitute the value of y to the equation 1,
7x + 11(25-x) = 227
7x + 275 - 11x = 227
275 - 227 = 4x
x = 48/4
x = 12
Then y = 25 - 12
y = 13.
Therefore, the prices of ticket for adult's and children are $12 and $13 respectively.

In a state, 30% of all people own a scooter, and 41% of all people have a skateboard and bicycle. Find the probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle? Round answer to nearest tenth and include percent sign.
Answer: 50%.
Step-by-step explanation: If someone went shopping for a scooter and it was $49.99 dollars but saw a skateboard for $14.99, they would choose the skateboard because it’s cheaper. If someone else went to the store because they wanted a skateboard but then they saw a scooter for $23.99 and a bike for $19.99 there is a 50% chance they will choose the cheaper one. (I hope this ,add sense
The probability is given by the equation P = 12.3 %
What is Probability?The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible
Probability = number of desirable outcomes / total number of possible outcomes
The value of probability lies between 0 and 1
Given data ,
Let the probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle be P
Now , the equation will be
Let the probability of selecting a person owing a scooter A = 30 %
Let the probability of selecting a person owing a scooter A = 0.3
Let the probability of selecting a person owing a skateboard and bicylce be B = 41 %
Let the probability of selecting a person owing a skateboard and bicylce be B = 0.41
Now ,
Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle P = probability of selecting a person owing a scooter A x probability of selecting a person owing a skateboard and bicylce B
Substituting the values in the equation , we get
Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle P = A x B
Probability of choosing a person that has a scooter and then choosing another person sequentially who has a skateboard and bicycle
P = 0.3 x 0.41
P = 0.123
Hence , the probability is P = 12.3 %

Shannon's rain-catcher has 8 inches of water in it. Each day, 3 inches of water are added to the rain-catcher. Let y represent the total number of inches of water in the rain-catcher after x days. Express the equation in the form of y=mx+b .
Answer:
y= 3x + 8
Step-by-step explanation:
y = mx + b
m = 3 inches of water added each day
x = 8 inches of water at start
y= 3x + 8 is the required equation.
What is an equation?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given that, Shannon's rain-catcher has 8 inches of water in it. Each day, 3 inches of water are added to the rain-catcher.

Mr. Smith drove for 45 minutes at a speed of 40 km/h. He stopped for 15 minutes for a coffee break and then he drove for 2 hours at a speed of 75 km/h. What was his average speed for the entire journey?
Answer:
60 km/h
Step-by-step explanation:
Average speed is total distance over total time.
Total distance: 30 + 0 + 150 = 180 km.
Total time: 0.75 + 0.25 + 2 = 3 hrs.
180/3 = 60/1
7. Reggie deposited $1,000 into an account that earns 5% compound interest monthly. If he does not deposit anymore into the account or take any money out of the account how much will the account be worth in 10 years?
Given :
Reggie deposited $1,000 into an account that earns 5% compound interest monthly.
To Find :
Worth of money after 10 years.
Solution :
We know, final amount is given by :
[tex]A=P(1+\dfrac{r}{n})^{nt}[/tex]
Here, P = initial balance
r = interest rate
n = number of times interest applied per time period
t = number of time period
Putting all given values in above equation, we get :
[tex]A=1000(1+\dfrac{0.05}{12})^{12\times 10}\\\\A =\$1647.01[/tex]
Therefore, money in his account after 10 years is $1647.01 .
Hence, this is the required solution.
