Talking about a parallelogram, we know that:
opposite sides and angles are congruent
in the picture below:
∠A = ∠C
AD = BC
if one angle is right, then the rest are right as well (making it a rectangle/square)
The consecutive angles are supplementary (meaning they add up to 180)
A + D = 180°
If y and w are consecutive angles, then
w = 180 - 32
=148°
If they are opposite angles, w = 32° (congruent angles)
2x + 5y = 34
x+2y = 14
Multiply the second equation by two to create like terms for one variable.
2(x+2y = 14)
2x + 4y = 28
2x + 5y = 34
2x + 4y = 28 -- Subtract.
y = 34.28 = 6
Solve for x
x + 2(6) = 14
x + 12 = 14
x = 2
Check:
2 + 2(6) = 14
2 + 12 = 14
14 = 14
Answer:
X = 2
Y = 6

Step-by-step explanation:

Substitute 7 for x in the given equation

Answer:
C) m = -63 is your answer
Step-by-step explanation:
Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.
Multiply 3 to both sides
-21 = (m/3)
(-21)(3) = (m/3)(3)
m = (-21)(3)
Combine like terms. Simplify.
m = -21 * 3
m = -63
C) m = -63 is your answer
