The answer would be choice C.
Perpendicular lines cross each other and form a right angle as you can see marked in the third picture.
Answer:
9
Solution:
Write it in an algebraic form (x is your number)
2x-11=7
Now solve
2x=7+11=18
X=18/2=9
Answer:
No Solutions.
Step-by-step explanation:
I will solve your system by substitution.
3y−3=3x; −3x+3y=−57
Step: Solve 3y−3=3x for y:
3y−3+3=3x+3 (Add 3 to both sides)
3y=3x+3
(3y/3=3x+3)/3
(Divide both sides by 3)
y=x+1
Step: Substitute x+1 for y in −3x+3y=−57:
−3x+3y=−57
−3x+3(x+1)=−57
3=−57 (Simplify both sides of the equation)
3+(−3)=−57+(−3) (Add -3 to both sides)
0=−60
Answer:
Step-by-step explanation:
∠3 = 180 - ∠1 {linear pair}
= 180 - 105
= 75°
∠2 = ∠3 {Corresponding angles"
∠2 = 75
Answer:
7/6
Step-by-step explanation:
4/6 divided by 8/14
4/6 * 14/8
56/48
Simplified: 7/6
