Answer:
x = 3/4 n
Step-by-step explanation:
-3(x+n)=x
Distribute
-3x-3n = x
Add 3x to each side
-3x-3n+3x= x+3x
3n = 4x
Divide by 4
3/4n = 3x/3
3/4 n = x
Answer:
98
Step-by-step explanation:
x(o) + 1(o) = 180(o)
∠2° = ∠x°
∠1° = ∠3°
Answer:
70% = 
20% = 
Step-by-step explanation:
We know that x% is represented by the fraction 
.
Now, in the first part, we are given two percentages 75% and 70%.
Now, 75% = 
and 70% =
Therefore, the second option is correct.
Again, in the second part, we are given two percentages 20% and 25%.
Now, 20% =
and 25% = 
Therefore, the third option is correct. (Answer)
Answer:
B or 108
Step-by-step explanation:
we know that the line splits the 90 angle, so the other side is 54
Since it is a isosceles triangle, the base angles are the same and they are both 54 degrees.
The sum of all the angles in a triangle is 180, so 180-54-54 is 72.
Since the line intersecting the triangle is a straight angle 180, we do 180-72=108
Answer:
Step-by-step explanation:
perp. -1/3
y - 2 = -1/3(x + 9)
y - 2 = -1/3x - 3
y = -1/3x - 1
answer is C
