Answer:

The cost of one burger is $2.95

The cost of one fry is $1.45

Step-by-step explanation:

Let

x----> the cost of one burger

y---> the cost of one fry

we know that

5x+2y=17.65 ----> equation A

2x+3y=10.25 ----> equation B

Using a graphing tool

Remember that the solution of the system of equations is the intersection point both graphs

The intersection point is (2.95,1.45)

see the attached figure

therefore

The cost of one burger is $2.95

The cost of one fry is $1.45

Solution -

In triangle PSQ and SQR

Angle PSQ = Angle SQR ( Interior Angle form by the parallel lines are equal i.e PQ is parallel to QR)

Angle P = Angle R (given)

SQ = SQ ( common)

PSQ = SQR ( prove above)

By ASA Congruence criteria Triangle PQS is congruent to triangle QRS
