Answer:
The numbers are 3, 12 and 5.
Step-by-step explanation:
Let the numbers =x, y and z.
The sum of three numbers is 20 implies x+y+z=20----------------i
The second number is 4 times the first implies y=4x--------------ii
The sum of the first and the third is 8 means x+z=8---------------iii
from (i), z=20-x-y---------iv
Put (iv) in (iii),
x+20-x-y=8
20-y=8
y=20-8=12
y=12
Put y=12 in (ii)
4x=y
x=y/4 = 12/4 = 3
x=3
Put x=3 and y=12 in (iv)
z=20-3-12=5
z=5
Therefore, the numbers are 3, 12 and 5.
To estimate the unit rate, we should round the 5.79 to 6. This makes it much simpler to solve as 6 is a multiple of 12. The unit rate, in this case, is the price of 1 pair of socks. We can find this by dividing both the price and pairs of socks by 12. When we do this, we can see that each pair of socks is approximately $0.50.
For the first question, you need to count all of your choices. Kepp in mind, it will be a fraction. Then count all of your "V6".
12/24 = 1/2
