Burger joint is celebrating their grand opening. for 2 milkshakes and 3 burgers, the cost is $13. for 5
milkshakes and 7 burgers, the cost is $31.
what is the cost of 1 burger and 1 milkshake?

For this case we propose a system of equations:

x: Let the variable representing the cost of a milkshake

y: Let the variable representing the cost of a burger

According to the statement we have:

We multiply the first equation by -5:

We multiply the second equation by 2:

We have the following equivalent system:

We add the equations:

Thus, the cost of a burger is $3.

So, the cost of a milkshake is $2

Burger: $3

Milkshake: $2

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
