Answer:
<u><em>54.86 or 55, rounded to a whole number</em></u>
Step-by-step explanation:
(128*3) = 384
384/7 = 54.86
This is not a whole number
Answer:
<em>-90 degrees</em>
Step-by-step explanation:
Draw a segment from the origin, point O, to point R. Draw a segment from the origin, point O, to point R'. The angle of rotation is the angle between segments OR and OR'.
The slope of segment OR is 2/3.
The slope of segment OR' is -3/2.
The slopes are negative reciprocals, so the segments are perpendicular.
The angle between the segments is 90 degrees. The rotation is counterclockwise, so it is a negative number of degrees.
The angle of rotation is -90 degrees.
Answer:
6
Step-by-step explanation:
The equation for this would be:
n+8=14, since we are adding 8 to a number and getting 14
To solve, isolate the variable n, by subtracting 8 from both sides
n+8=14
n+8-8=14-8
n=6
The number is 6
-3/12 - 20/12 is equivalent to -1/4 - 5/3
