Answer:
Step-by-step explanation:
First you determine the variables x and y as:
x: the value for student tickets
y: the value for chaperone tickets.
Knowing that student tickets cost $ 2 more than companion tickets, it is represented by the equation:
x= y +2
On the other hand, there were 59 students and 6 companions. And the total cost of admission for the group was $ 508, that is to say that what all the students and the companions have paid adds up to $ 508. Expressed by an equation:
59x + 6y = 508
Then the system of equations to solve and thus obtain the price of a student ticket and the price of a companion ticket is:
Solving for x, the price of a student ticket:
Rearranging the first equation,
y = x - 2
Replacing in the second equation and solving for x:
59*x + 6*(x -2)=508
59*x + 6*x -12=508
65*x -12=508
65*x= 508 +12
65*x= 520
x=8
The cost of a student ticket is 8$
Answer:
139
Step-by-step explanation:
He originally had 147 books and threw 8 into a pond.
147-8=139
Answer:
When you input values for x, you can determine a single output for y. ... Instead, you could use f(x) or g(x) or c(x). This can ... P = 4s, as the function p(x) = 4x, and the formula for area, A = x2, as a(x) = x2. ... You read this problem like this: “given f of x equals 4x plus one, find f of 2. ... f(2) = 4(2) + 1 = 8 + 1 = 9 ... f(2) = 12 + 4 + 1.

Answer:
45
Step-by-step explanation:
He spent 4/5 out of 5/5
4/5 = 36 to find the whole we cross multiply the equation
let x represent the whole
4/5 = 36/x
5*36 = 4x
180 = 4x divide both sides by 4
x = 45
