Tickets to the concert were 2.50 for adults and $1 for students. $1200 was collected and 750 tickets were sold. write a system of linear equations that can be used to find how many adults and how many students attended. how many students attended?

300 adults and 450 students

Step-by-step explanation:

We can set-up a system of equations to find the number of adults. We know students and adults attended. We will let s be the number of students and a be the number of adults. Since 750 people attended, then s+a=750.

We also know they made $1200 and adult tickets cost $2.50 and student tickets cost $1. We can write 1s+2.5a=1200.

We will solve by substituting one equation into the other. We start by solving the first equation for c. s+a=750 becomes s=750-a.

Now we substitute s=750-a into 1s+2.5a=1200. Simplify and isolate the variable a.

This means that 300 adults attended and 450 students attended since 300+450=750.

Step-by-step explanation:

0 all triangles must add up to 180 degrees.

the answer is here: : )

:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
