Answer:
3B
Step-by-step explanation:
The greatest common factor is the greatest number that will divide two values. We have two values 3B and 30B. Each has numbers which multiply together to give the number. We need to find the highest value or most in common they share. Each has the factors:
3B: 1,3,B
30B: 1, 3, 5, 6, 10, B
Both have 3 and B has factors. Our GCF is these two factors.
Answer:
Second florist makes bouquets at a faster rate.
Step-by-step explanation:
To compare both find the similar ratio or bouquets in one hour.
<u>Similar ratio:</u>
One florist:
16 bouquets in 5 hours is same as
192 bouquets in 60 hours (Just multiplied by 12)
Second florist:
40 bouquets in 12 hours is same as
200 bouquets in 60 hours (multiplied by 5)
Now both have similar hours to compare and look like second florist can make more bouquets than one florist.
<u>Work done in one hour:</u>
One florist:
16 bouquets in 5 hours meaning 3.2 bouquets in 1 hour (divide by 5)
Second florist:
40 bouquets in 12 hours meaning 3.33 bouquets in 1 hour (divided by 12)
Again second florist have higher rate.
Work:
21x-7y=12
-7y=12-21x
y= -12/7+3x
Point: (1,-3)
y-y1=m (x-x1)
y+3= -12/7 (x-1)
y+3= -12/7x + 12/7
y= -12/7x -9/7
The equation is y= -12/7x- 9/7
