Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
Okay, so you know that the perimeter of the pen is 28 feet. Now we need the separate side lengths.
P = 28 ft.
Length = x
Width = (1/2)x + 2
So now we can plug in the little equations of length and width into a perimeter formula:
2(x) + 2((1/2)x + 2) = 28
Distribute the 2's and solve as needed.
2x + x + 4 = 28
3x + 4 = 28
3x = 24
x = 8
To find the width, just plug in 8 for x in our little equation:
(1/2)(8) + 2
= 6
So, the length is 8 feet and the width is 6 feet.
The value of x is x=1/10
This can also be written as:
X=0.1
X=10^-1
Answer:
They have won 28
Step-by-step explanation:
The team has lost 1/5 of their games. You can do how many they have lost, 7, times the amount of the denominator, 5. Doing this gives you 35, the TOTAL games played. Since we are looking for the games won, you do the total, 35, minus the games lost, 7. You get 28.
