so what you would do is 20 x 12 and see what you get and the subtract it from 900 and then see what number would take you to 900
Answer:
Step-by-step explanation:
Since they are adjacent the sum of the angles must equal 180 degrees.
17x+4+2x+5=180
19x+9=180
19x=171
x=9 making 17x+4=17(9)+4=157 degrees and 2x+5=2(9)+5=23 degrees
So the two angles are 23 and 157
Answer:
13 nights
Step-by-step explanation:
To figure this out you first need to find out how many more centimeters to get to 36
36cm-23cm= 13 cm
If he needs to knit 13 more centimeters and he can knit 1 centimeter each night it would take him a total of 13 nights in order to knit a total of 36 centimeter scarf

Answer:</h2>
The image to the question is missing, but I found a matching image, which is attached to this solution
Answer:
3 minutes = 13 dots
100 minutes = 401 dots
t minutes = 4(t) + 1 dots
Step-by-step explanation:
From the image, the following can be noticed:
time (Mins) dots
0 1
1 5
2 9
The pattern gotten from this progression is that, if the time is multiplied by 4, and the result added to one, the result will be the number of dots.
hence, when the time is 0 minutes:
0 × 4 = 0
0 + 1 = 1 ( 1 dot)
when the time is 1 minute
1 × 4 = 4
4 + 1 = 5 (5 dots)
when the time is 2 minutes
2 × 4 = 8
8 + 1 = 9 ( 9 dots)
Therefore,
when the time = 3 minutes
3 × 4 = 12
12 + 1 = 13 dots
at 100 minutes:
100 × 4 = 400
400 + 1 = 401 dots
at t miutes
t × 4 = 4t
4t + 1 = number of dots
Therefore number of dots at t minutes = 4(t) + 1
<span>The <u>correct answer</u> is:
The midpoint of a segment.
Explanation<span>:
To construct a line parallel to another line through a given point, the first thing you do is fold the given line onto itself, making sure that the given point is on the fold. This is the same construction used to find the midpoint of a segment.
Unfold the paper, and the crease made with the fold creates a line through the given point and given line. Fold this new line (crease) onto itself, making sure the given point is in the fold. This is again the same construction used to find the midpoint of a segment, and this creates our parallel line through our given point.</span></span>
