What is the value of x?
Enter your answer in the box
Answer:
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.
Step-by-step explanation:
What is the value of x?
Answer:
x=71
Step-by-step explanation:
38+x+x=180
x+x=142
2x=142

In 2006 the average ticket price for a national football league game was 62.38. Since then the cost has increased an average of $2.54 per year. Write a linear equation to represent the cost of C of an NFL ticket y years after 2006.
Answer:
y = 2.54x + 62.38
Step-by-step explanation:
Let x represent the duration or stipulated years after the year 2006
Let y represent the amount of ticket that is sold
Let m represent the average increase in the price every year
y = mx + c
y = 2.54 × x + 62.38
y = 2.54x + 62.38
Answer:
C=2.54y+62.38
c=2.54y+62.38
C=62.38+2.54y
or
c=62.38+2.54y

The zoo has 12 Emperor penguins, which makes up 24% of all penguins at the zoo. How many penguins live at the zoo?
Answer:
[tex]50[/tex] penguins
Step-by-step explanation:
Let [tex]p[/tex] = number of penguins at the zoo
[tex]24\%p=12[/tex] (Is given that 12 Emperor penguins at the zoo make up 24% of total penguins)
[tex]0.24p=12[/tex]
[tex]p=12\div0.24[/tex]
[tex]p=50[/tex]
∴ There are [tex]50[/tex] penguins at the zoo

At the King School, 55% of the students take a bus to school. If 220 students take a bus to school, how many students are there in total?
Answer:
400 student
55/100 * x(unknown) = 220
55x/100 =220
CROSS MULTIPLY
55X = 22000
X = 22000/55
X = 400
The total number of students at the King School is 440.
Given that, at the King School, 55% of the students take a bus to school.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the total number of students be x
So, 55% of x =220
⇒ 55/10 ×x=220
⇒ 0.55x=220
⇒ x=220/0.55
⇒ x=440
Therefore, the total number of students at the King School is 440.

18 vocabulary words learned in 2 hours; 27 vocabulary words learned in 3 hours
Answer: They are equivalent
Step-by-step explanation:
Here is the complete question:
18 vocabulary words learbed in 2 hours 27 vocabulary words learned in 3 hours Are they equivalent? Why
From the question, we are informed that 18 vocabulary words are learned in 2 hours. The number of words learned per hour will be:
= 18/2
= 9 words per hour.
27 vocabulary words learned in 3 hours. The number of words learned per hour will be:
= 27/3
= 9 words per hour.
Since they both have identical number of words learned per hour, it means that they're equivalent.
An ammonia and water mixture fills a five-gallon container. Eighty percent of the mixture is ammonia, but some of the mixture will be drained and replaced with pure water. If a five-gallon mixture of fifty percent ammonia is desired, how many quarts of the mixture need to be drained before the water is added, given that 4 quarts equals a gallon
Answer:
The volume of the 80% ammonia that is to be drained before water is added is 7.5 quartz
Step-by-step explanation:
The volume of the ammonia and water mixture = 5 gallons
The percentage of ammonia in the mixture = 80%
The volume of ammonia desired = 5 gallons
The percentage concentration of ammonia desired = 50%
The diluting solution = Pure water
The measure of 4 quarts = 1 gallon
Therefore, we have, by equivalence solutions;
80% × x gallon = 50% × 5 gallons
x gallon = 50% × 5 gallons/(80%) = 3.125 gallons
x = 3.125 gallons
The volume of the 80% ammonia that is to be drained = 5 gallons - 3.125 gallons = 1.875 gallons
4 quarts = 1 gallon
1 gallon = 4 quarts
∴ 1.875 gallons = 4 × 1.875 quartz = 7.5 quartz
The volume of the 80% ammonia that is to be drained before water is added = 7.5 quartz
Answer:
7.5

(triangles) if FGH= QRS, find the measure of
Answer:
Option (4)
Step-by-step explanation:
From the picture attached,
ΔFGH ≅ ΔQRS
Therefore, ∠F ≅ ∠Q
m∠F = m∠Q
(2x + 10)° = (3x + 1)°
3x - 2x = 10 - 1
x = 9
m∠Q = (3x + 1)°
= 27 + 1
= 28°
Option (4) will be the correct option.

A train leaves the station at time = 0. Traveling at a constant speed, the train travels 330 kilometers in 3 hours. Answers parts a and b. A. Write a function that relates the distance traveled d to time t. The function that relates the distance traveled d to the time is.
Answer:
The function that relates the distance traveled d to the time t is
f(t) = 110t, where d = f(t)
Step-by-step explanation:
From the question, we were told that the train is At a constant speed, the train travels 330 kilometers in 3 hours
We were told to write function that relates the distance traveled d to the time t, we can do this by writing a linear equation with those functions
Since we are told that the train travels 330 kilometers in 3 hours, then we can say the train travel (330/3) kilometers in 1 hour which means it travel 110 kilometers in 1 hour
Then d= 110t---------------eqn(1)
If if t = 0, then d = 0, as well since at t=0 the train is at the station
At t = 1 then d = 110.
From equation (1) d can be replaced by f(t) then we have
f(t) = 110t----------------eqn(2)
Now we replace d by f (t), because d = f t):
f(t) = 120t
Therefore, The function that relates the distance traveled d to the time is f(t) = 120t
simplify:4.6t + 7.1s + 12.8t - 1.6s
Answer:
17.4t+5.5s
