The answer is 5
Explanation:
The 9 by 15 picture is similar to the 3 by x picture, meaning its the same shape but not the same size.
Since we know what the width is for the first picture we have to get the width of the second picture to equal the same width without changing the shape.
To do that you divide BOTH 9 and 15 by 3
And you get 3 and 5.
Hope this help you understand better.
1/5n - 12 = -7
or you can say
n/5 - 12 = -7
then if you solve...
n/5 - 12 = -7
+12 +12
n/5 = 5
times 5 on each side
n = 25
Answer:
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and they are supplementary(sum=180°).
Step-by-step explanation:
Given:
Line 
Line 
is traversal.
By angle properties we can name the angle relationship of given angle pairs.
are corresponding angles and are congruent to each other.
are alternate exterior angles and thus congruent to each other.
are interior angles on the same side, and thus they are supplementary.
2(81-56-27+3)
162-112-54+3= -1
