We know that when
and
the midpoint of the line segment AB is given by:
Here
and
so:
Step-by-step explanation:
The union of two sets contains all the elements contained in either set,
The intersection of two sets contains only the elements that are in both sets.
P r o p o r t i o n s
3:4 = 7
3/198 = 7/x
solve for x using cross multiplying
3/198 = 7/x
198(7) = 3x
1386 = 3x
/3 /3
462 = x
Therefore, there are 462 workers.
Proof:
3/198 = 4/x
198(4) = 3x
792 = 3x
/3 /3
264 = x
264 + 198 = 462.
264 / 4 = 66
198 / 3 = 66
462 / 7 = 66
Answer:
Line 1 and 4
Step-by-step explanation:
Perpendicular lines are easy to see once you realize that their slopes, the numbers in front of the x, are inverses. Line 1 and 4 are inverses.
1/3 and 3
Boom.
