This would be true because it shows that p equals either a or b and it also shows that p equals a which is true because it is one of the independent choices.
Answer:
8y=8 or 4y=-4
Step-by-step explanation:
1.)-2(x+3y=-1)
2x+2y=6
2.)-2x+6y=2
2x+2y=6
3.)6y=2
2y+6
4.)8y=8 (If adding) or 4y=-4 (If subtracting)
Answer:
x = 60
Step-by-step explanation:
Vertical opposite angles are formed when two straight lines intersect each other.
Given that AD and CD are two straight lines intersecting at O, the two vertical opposite formed are, ∠AOD and ∠COB. Therefore:
∠AOD = ∠COB (Vertical opposite angles are congruent)
∠AOE = 90° (right angle)
∠DOE = x
∠COF = 30°
∠BOF = 2x
m∠AOE + m∠DOE = m∠AOD (angle addition postulate)
90 + x = ∠AOD (Substitution)
m∠COF + m∠BOF = m∠COB (Angle addition postulate)
30 + 2x = ∠COB
m∠AOD = m∠COB (vertical opposite angles)
90 + x = 30 + 2x (Substitution)
Collect like terms
90 - 30 = 2x - x
60 = x
x = 60

Answer:
54
Step-by-step explanation:
Since there are parantheses or however you spell them, by using PEMDAS, we do the parantheses first.
23 - 1 = 22
Now, we do the addition.
22 + 32 = 54
