Answer:
The basketball game sold 439 adult tickets and 858 student tickets.
Step-by-step explanation:
A system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is, in the systems of equations, one must look for the values of the unknowns, with which when replacing, they must give the solution proposed in both equations.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,047 was collected on the sale of 1,291 tickets.
With "x" the number of adult tickets sold and "y" the number of student tickets sold, you have the following system of equations:
[tex]\left \{ {{x+y=1291} \atop {5*x+1*y=3047}} \right.[/tex]
Through the substitution method, you must solve for one of the unknowns in one of the equations and substitute its value in the following one: in this case you solve for the variable y from the first equation:
y=1291 -x
and you replace in the second equation:
5*x + 1291 - x= 3047
Solving, you get:
5*x-x= 3047 - 1291
4*x= 1756
x= 1756÷4
x=439
Replacing this value in the expresion y=1291 -x you get:
y=1291 -439
y= 858

Does 2,4,5 make a right triangle
Answer:
No
Step-by-step explanation:
The formula is a² + b² = c²
2² + 4² = 5²
4 + 16 = 25
20 ≠ 25
20 is not equal to 25, so 2, 4, 5 does not make a right angle triangle.
Answer: Yes.
Step-by-step explanation:
2 + 4 > 5
2 + 5 > 4
4 + 5 > 2

A ticket for a seat at a school play costs £2.95
There are 21 rows of seats.
There are 39 seats in each row.
The school will sell all the tickets.
Work out an estimate for the total money the school will get.
Answer:
Answer vary :
2.95(21 times 39) = $2,416.05
Step-by-step explanation:
honestly in my opinion that the answer. so we’re trying to find out how much money the school will earn.
if each seat cost 2.95 we need to find out how many seats are their?
-21 times 39 = 819
we multiplied the rows and seats find out how many seats their are and the answer is 819.
after you do that now we have to find out how much money they will earn from selling all 819 seats.
-819 times 2.95 = 2,416.05
we then multiplie all of the seats wich is 819 seats by 2.95 wich is the cost of one seat and got 2,416.05, and that’s the answer we’ve been looking for.
and that’s how I got my answer.
The total money school will get is £2416.05 on a play.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given:
A ticket for a seat at a school play costs £2.95
There are 21 rows of seats.
There are 39 seats in each row.
That means,
there are total 21 x 39 = 819 seats.
So, the total money the school will get,
= 819 x £2.95
= £2416.05
Therefore, school makes £2416.05 on a play.

Find the solution of the system of equations -7x-3y=-20 3x+6y=-15
9514 1404 393
Answer:
(5, -5)
Step-by-step explanation:
I like a graphing calculator for quickly finding a solution to a system of equations. It shows the solution to be (5, -5).
__
We can add the second equation to 2 times the first to eliminate the y-variable.
2(-7x -3y) +(3x +6y) = 2(-20) +(-15)
-11x = -55 . . . . . collect terms
x = 5 . . . . . . . . . divide by -11
Substituting this value into the second equation, we have ...
3(5) +6y = -15
6y = -30 . . . . . . . . subtract 15
y = -5 . . . . . . . . . . divide by 6
The solution is (x, y) = (5, -5).
