Answer:
XXL = $19.75
Box of Breadstick = $3.5
Step-by-step explanation:
Given that:
Let :
cost per XXL pizza = x
Cost per box of bread stick = y
4x + 2y = 86 - - - (1)
6x + 4y = 132.50 - - - (2)
From (1): Divide (1) by (2)
2x + y = 43 - - - (3)
y = 43 - 2x
Substitute y = 43 - 2x into (2)
6x + 4(43 - 2x) = 132.50
6x + 172 - 8x = 132.50
-2x + 172 = 132.50
-2x = 132.50 - 172
-2x = - 39.50
x = $19.75
y = 43 - 2x
y = 43 - 2(19.75)
y = $3.5
Answer:
ASA Congruence Postulate
Step-by-step explanation:
Here if we clearly observe ∠DAC=∠BCA and ∠DCA=∠BAC
Also AC is a common side to both the triangles .
So by ASA congruence postulate we have that the ΔADC and ΔCBA are congruent.
ASA congruence postulate states that if two triangles have two angles and an included side same then both the triangles are congruent.
