Answer:
3x(2+n)+[7+n]
Step-by-step explanation:
The answer is kind of self-explanatory, but think of it this way. If n=5, then the equation would be 3x(2+5)+[7+5]. First we would solve 2+5 which is 7. Then we would do 7+5 which is 12. We are now left with 3x7+5.

Brandon goes to the fair with $25.00. He spends $4.00 to get in and the rest on tickets for rides. Each ride ticket costs $1.50. How many ride tickets does brandon buy? Explain how you got your answer below.
Answers
Answer:
14
Step-by-step explanation:
$25.00 - $4.00 = $21.00
$21.00 / $1.50 = 14
Answer:
14 ride tickets
Step-by-step explanation:
He has $25, and spends $4. So 25 - 4 = 21. Each ride ticket is $1.50. So 21 ÷ 1.50 = 14

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?
Answers
Answer:
96 miles
Step-by-step explanation:
The distance from the amusement to jack's home is x (mile, x>0)
jack's family went to the amusement park at: 9 + x/60
On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph
they left the amusement park at: 20 - x/40
have the following equation:
(20 - x/40) - (9+ x/60) = 7
⇔ 4 = x/40 + x/60
⇔ x = 96
so the distance from the amusement park to jack's home is 96 miles
Yesterday Christopher sold 35 pounds of apples and 34 pounds of bananas for a total revenue of $163.50. Today he sold 15 pounds of apples and 17 pounds of bananas for a goal revenue of $76.75. Determine the price of each pound of apples and the price of each pound of bananas
Answers
Answer:
Step-by-step explanation:
35 a + 34 b = 163.50 (given)
15 a + 17 b = 76.50 (given) multiply this equation by -2
-30 a - 34 b = -153.00 now add this equation to the first equation t get
5 a = 10.50 solve this for a (apple's price) then sub this value into one of the equations to find banana price, b.

Find the lenght of side BC. give your answer to 3 significant figures
Answers
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )

The sum of five consecutive even integers is 220. Find the middle value of the five consecutive integers.
Answers
Answer:
44Step-by-step explanation:
If we have odd number of consecutive numbers increasing by the same value (2) then the middle value of them is their mean:
220:5 = 44
Of course you can find them to be sure:
Consecutive even integers increase by 2.
So if 2x is the smallest of them (x is an integer), then the numbers are:
2x, 2x+2, 2x+4, 2x+6, 2x+8
So their sum: 10x+20
10x + 20 = 220 ⇒ 10x = 200 ⇒ 2x = 40
So the numbers are: 40, 42, 44, 46, 48
Answer:
44

Someone please help me asap. I’m confused and need help. Complete the table using the function n = 9b + 19
Answers
answer: you would just substitute all of the values you see for b into the equation where there's a b
Answer:
55; 64; 73
Step-by-step explanation:
In the table, they provide a b value. Basically, you plug in the value of b they give you into the expression n = 9b + 19
if b = 4:
n = 9(4) + 19
n = 36 + 19
n = 55
if b = 5:
n = 9(5) + 19
n = 45 + 19
n = 64
if b = 6:
n = 9(6) + 19
n = 54 + 19
n = 73
Check your work with the last numbers in the table. They say the value of n = 82 when b = 7 so try it
if b = 7:
n = 9(7) + 19
n = 63 + 19
n = 82

Inspectors for a hospital chain with multiple locations randomly select some of their locations for a cleanliness check of their operating rooms. The inspectors check every operating room in the hospitals that were chosen. What sampling method was used?
Answers
Answer:
Cluster Random Sample
Step-by-step explanation:
The operating rooms were divided into (hospital locations) and inspectors sampled every operating room from some of the groups.
Sampling method is the method where the subset of an overall population is selected.
The sampling method used was cluster sampling
From the question, we understand that:
The inspectors select some locationsThen all selected locations was checkedThe above illustrates cluster sampling.
This is so because, cluster sampling involves breaking down a population into smaller size.
In this case, the smaller size are the locations that were selected.

Solve for x in the following equation:
kx = m + nx
Answers
Answer:
x = [tex]\frac{m}{k-n}[/tex]
Step-by-step explanation:
Given
kx = m + nx ( subtract nx from both sides )
kx - nx = m ← factor out x from each term on the left side
x(k - n) = m ← divide both sides by (k - n)
x = [tex]\frac{m}{k-n}[/tex]
Solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]
Given:
kx = m + nx
We are require to make x the subject of the formula.Thus:[tex]kx = m + nx[/tex]
Subtract nx to both sides of the equation[tex]kx - nx = m + nx - nx\\\\kx - nx = m[/tex]
Factor out x on the left side[tex]x(k - n) = m[/tex]
Divide both sides by (k - n)[tex]\frac{x(k - n)}{k - n} = \frac{m}{k - n} \\\\x = \frac{m}{k - n}[/tex]
Therefore, solving for x in the equation, kx = m + nx, we would make x the subject of the formula to solve for x as: [tex]\mathbf{x = \frac{m}{k - n}}[/tex]

What is m∠PQR?
The PS is line segment. Q is the point between segments PS. QR is another line segment passes through segment PS. The angle PQR is (3x + 5) degree and angle SQR is (x + 3) degree.
Answers
Answer: m∠PQR = 134°
Step-by-step explanation:
Given: PS is line segment. Q is the point between segment PS. QR is another line segment passes through segment PS.
That means ∠PQR and ∠SQR are linear pair [Linear pair is a pair of two angles made on one line and their sum is 180°]
⇒ ∠PQR + ∠SQR = 180° (i)
Since, ∠PQR is (3x + 5)° and ∠ SQR is (x + 3)° [given]
Put this in (i), we get
(3x + 5)° + (x + 3)° = 180°
⇒ 3x + 5 + x + 3 = 180
⇒ 4 x + 8 = 180
⇒ 4 x = 180-8
⇒ 4 x = 172
Divide both sides by 4
⇒ x= 43
So, ∠PQR= (3(43) + 5)° = 134°
Hence, m∠PQR = 134°
The measure of m ∠PQR is 134 degrees.
GivenPS is a line segment.
Q is the point between segment PS.
QR is another line segment that passes through segment PS.
Which property of the triangle is used to solve the value of x?The sum of two angles made on one line is equal to 180 degrees.
[tex]\angle \rm PQR + \angle SQR = 180[/tex]
Where the angle QPR is (3x + 5) degree and angle SQR is (x + 3) degree.
Substitute all the values in the equation
[tex]\angle \rm PQR + \angle SQR = 180\\\\(3x+5) + (x+3) =180\\\\3x+5+x+3=180\\\\4x+8=180\\\\4x=180-8\\\\4x=172\\\\x = \dfrac{172}{4}\\\\x =43[/tex]
The value of x is 43 degrees.
Therefore,
The measure of m ∠PQR is;
[tex]\rm m \angle PQR = 3x+5 = 3(43) + 5= 129+5=134[/tex]
Hence, the measure of m ∠PQR is 134 degrees.

You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a giant candy snake for $12.50. When you leave, you have $8.75 left in your wallet. How much did each candy bar cost? Write the equation to represent the scenario. 8.75 - x - 12.50 = 25.00 25.00 - 3x - 12.50 = 8.75 25.00 - 3x - 8.75 = 12.50 25.00x - 12.50 = 8.75
Answers
Answer:
The cost of a candy is $1.25Step-by-step explanation:
given the total amount at hand is $25
let the price of candy be x
then the cost of 3 candy will be 3x
the cost of a candy snake is $12.50.
balance at hand after the end of buying $8.75
the total expenses summed up must equal the initial amount at hand which is $25
the expression for the scenario is 3x+12.5+8.75=25
3x+21.25=25
3x=25-21.25
3x=3.75
x=3.75/3
