Admission to the state fair is $12, and each ride ticket costs $3.50. Write an
expression to represent the situation and explain what the variable means.
3.50t + 12 where t represents the number of ride tickets
3.50a + 12 where a represents the cost of admission
12a + 3.50 where a represents the cost of admission
12t + 3.50 where t represents the number of ride tickets
Answer : 3.50t + 12
Step - by - step explanation :
the reason why I think the answer is " 3.50t + 12 " is because . . . since the admission to the state farm is only ONCE - there doesn't need to be a variable there to tell us that it MIGHT repeat more than once. and because we don't know how many ride ticket will be purchased - there is a variable there to tell us unknown.

What is an equation of the line that passes through the point (6,-4) and isperpendicular to the line 22 - y = 5?
slope y-intercept form of an equation for a line that has an x-intercept of "-3" and goes through (-2,2)
Answer:
y=2x+6.
Step-by-step explanation:
1) the condition 'an x-intercept of "-3"' means the point A with the coordinates (-3;0), then it is possible to make up the required equation according to the rule (the coordinates (-2;2) belong to the point B):
[tex]2) \ \frac{x-X_B}{X_A-X_B}=\frac{y-Y_B}{Y_A-Y_B}, \ where \ X_A=-2;Y_A=2;X_B=-3;Y_B=0.[/tex]
after the substitution the coordinates into the rule:
[tex]\frac{x+3}{-2+3} =\frac{y-0}{2-0}; \ => \ \frac{x+3}{1}=\frac{y}{2}; \ => \ y=2x+6.[/tex]
The sum of 139 and the product of a number raised to the third power and 17. In symbols, the phrase is written as.
Answer:
y = 139 + x³ + 17
Step-by-step explanation:
The word "sum" means the amount resulting from addition in an equation. This means that we are adding all of these numbers together.
The word "product" means the amount resulting from multiplication in an equation, this means we need to find the product of a number multiplied by itself three times. Since we don't know what number it is, we can use the variable 'x'.
So, you would be adding 139, the product of x³, and 17, which would be written as y = 139 + x³ + 17.
Ted likes to run long distances. He can run 20 kilometers in 95 minutes. How far will Ted run in 285 minutes? (numeric only) *
[tex]\boxed{\boxed{\Large \text{Ted will run 60 kilometres in 285 minutes.}}}[/tex]
Step-by-step explanation:Using the distance-time-speed relationship:
[tex]\boxed{\Large \text{speed = $\frac{\rm distance}{\rm time}$}}[/tex]
[tex]\boxed{\Large \text{distance = speed $\times$ time}}[/tex]
[tex]\boxed{\Large \text{time = $\frac{\rm distance}{\rm speed}$}}[/tex]
so if Ted can run 20 kilometres (distance) in 95 minutes (time), then his speed = 20 ÷ 95 = 4/19 km/min.
Using this result, to calculate how far Ted will run in 285 minutes, we can say that distance = 4/19 × 285 = 60 kilometres.
∴ Ted will run 60 kilometres in 285 minutes.

solve for y and x
2+3x-1=4y
And
2x-3=y
Answer:
x = 2.6, y = 2.2
Step-by-step explanation:
if 4y = 2 + 3x - 1 and
y = 2x - 3,
4y = 2 + 3x -1 and 4y = 8x - 12 so
8x - 12 = 2 + 3x - 1
so 5x - 12 = 1,
5x = 13,
x = 2.6
If x = 2.6,
y = 5.6 - 3
so y = 2.2

⦁ Avery noticed that 9/10 of the apples in a basket are red. There are 45 red apples in the basket. ⦁ Represent the situation with an equation. Use a for the variable. ⦁ Solve the equation in Part (a). Show your work. ⦁ What does the solution of the equation represent in the situation? ⦁
We want to write and solve an equation that represents the given situation. The equation we will find is (9/10)*a = 45, and its solution is a = 50.
So we know that 9/10 of the apples in the basket are red, and we know that there are 45 red apples.
Then, if we define a as the total number of apples, we know that (9/10) times a must be equal to 45, we can write this as:
(9/10)*a = 45
This is the equation that we must solve.
We can solve this if we multiply both sides by (10/9), it gives;
(10/9)*(9/10)*a = (10/9)*45
a = (10/9)*45 = 50
This means that there are 50 apples in the basket.

Jake's Argument is correct, adding zero (0) to an addend does not change a sum.
Addend is number which is added to another number.
For example:
y + 5 = 8
where;
5 is the addend number of y in the equation.Adding zero (0) to an addend does not change a sum. An example is present below;
5 + 3 = 8
add zero (0) to 3 and check if the final result will change;
5 + (3 + 0) = 5 + 3 = 8

The relations (1) to (4) represent the given parameter
Next, we test the options
Relation (1)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (2)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (3)
This relation is not a function
This is because it fails the vertical line test i.e. some output values all point to the same input value,
Relation (4)
This relation is a function
This is because the inputs all point to different output values

A middle school took all of its 6th grade students on a field trip to see a play. The students filled 1917 seats, which was 45% of the total number of seats in the theater. How many total seats were in the theater?
Answer:
4260 seats in the theater
Step-by-step explanation:
We write the equation 0.45x=1917, with x representing the total number of seats.
Multiply both sides by 100, we get 45x=191700.
Divide both sides by 45, we get x=191700/45
x=4260.
There are 4260 seats in the theater.
The total number of seats is the theater is 4,260.
Percentage:
The percentage is a ratio or fraction of 100 and can be calculated with the formula
Percentage = [tex]\frac{parts}{whole}.100[/tex]
How to calculate percentage?Here we have given that the 1917 seats is 45% of the total seats
Let the total number of seats available in theater is = x
Then 45 % of x = 1917
0.45 x = 1917
Multiply both the sides by 100 we have
45 x = 1917x100
x = [tex]\frac{191700}{45}=4260[/tex]
The final answer is 4,260 seats
