Answer:
Names that describe the shape- Trapezoid, Quadrilateral
Names that don't describe the shape- Square, Rectangle, Parallelogram and rhombus
Step-by-step explanation:
Answer:
B = 129
Step-by-step explanation:
Opposite angles of a parallelogram are equal (or congruent)
A and C are both 51.
All angles in a parallelogram equal 360
Take both the known angles and substract from 360, than divide by 2.
B = (360 - 51 - 51)/2
B = 129
Y = -3 + 5x ----------------- (1)
3x - 8y = 24 --------------- (2)
Solve by substitution. We will substitute equation (1) into equation (2):
------------------------------------------------------------
Substitute equation (1) into equation (2) :
------------------------------------------------------------
3x - 8y = 24 // Equation (2)
3x - 8(-3 + 5x) = 24 // Sub x = -3 + 5x
3x + 24 - 40x = 24 // Apply distributive property
-37x + 24 = 24 // Combine like terms
-37x = 0 // Take away 24 from both sides
x = 0 // Divide by -37 on both sides
Sub x = 0 into equation (1) :
y = - 3 + 5(0) // Sub x = 0
y = -3 // Combine like terms
-----------------------------------------------
Answer : The ordered pair is (0, -3).
