At lunch, Marc bought 2 quesadillas and 2 tacos for $10.16, and Jason paid $11.84 for 5 tacos and 1 quesadilla. What was the cost of each taco and quesadilla? Let the cost of a quesadilla be x and the cost of a taco be y.

X = 3.39 (Quesadilla)    Y= 1.69 (Tacos)

Step-by-step explanation:

You need to do systems of equations.

You take the quesadillas which is X and the Taco is Y and plug them into the equation with the total like this:

2x + 2y = $10.16

x + 5y = $11.84

solve and you get

(3.39, 1.69)

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.
