Find the greatest common factor. In this case it is 3. Divide each group by 3.
15÷3=5 quarters
30÷3=10 dimes
48÷3=16 nickels
Next count them by the coin's value:
5 × 0.25 = $1.25
10 × 0.10 = $1
16 × 0.05 = $0.80
Add them up:
= $3.05 in each group and there are three groups.
So, the greatest number of groups that he can make is 3; there will be 5 quarters, 10 dimes, and 16 nickels in each group, which is worth $3.05 in each group.
Answer:
i think is 7
Step-by-step explanation:
Let's calculate the slope of the A(3,1.5) and B(5, 2.5)
The formula of the slope m =(y₂-y₁)/(x₂-x₁)
m = (2.5 - 1.5)/(5 - 3)
m = (1)/(2) = 0.5
Aaron rate for mowing lawns is 0.5 Acre/Hour
Since 12 cost $27, you can use compatible numbers to make it ~$28. So, then for 6, it would cost $14 because you just halve everything. Is that what you are getting at?
