4 is not a factor of 30 because the factor of 30 is:
2*15
6*5
3*10
1*30
Vectors give us direction and distance. the first part of our ordered pair moves us in the x direction (left and right), and the second member of the ordered pair moves us in the y direction (up and down)
if you plotted each point along the move, you would go from (7,17) and move -1 in the x direction and 0 in the y, ending up at (6,17). From there, we move 2 in the x direction and 7 in the y, to (8,24).
basically we just add all of the x's together and the y's together since we are moving in a specific direction from a point to a new point.
so
x=7+-1+2+2=10
y=17+0+7+10=34
and we end up at (10,34)
Mixed number=4 8/10=4 4/5
improper fraction=48/10=24/5
Okay, one, how many pieces are in each package, and two, how many pieces does each person need?
Answer:
-4/5
Step-by-step explanation:
okay well first you have to make each fraction into improper fractions
2 1/2 going into 3/2 and -1 7/8 into -15/8
and then do keep change flip keeping the first fraction (3/2), changing the division sign into a multiplication sign, and flipping the numerator and denominator of -15/8 into 8/-15
3/2 × 8/-15 = 24/-30 = 4/-5
also
4/-5 = -4/5
