Answer: I dont know if im right for sure but the answer should be 4
Step-by-step explanation
8 goes into 2 4 times (8 divided by 2 = 4)
Each child ate 2 pieces (4-2=2)
so therefore for it to be 2 pieces left over there were 4 kids I think.
<u> P = 2 (L + B)</u>
Divide each side by 2 : P/2 = L + B
Subtract B from each side: <em>P/2 - B = L</em>
Answer:
![A = w^2 + 38w + 352](https://tex.z-dn.net/?f=A%20%3D%20w%5E2%20%2B%2038w%20%2B%20352)
Step-by-step explanation:
<u>Area of a Rectangle</u>
Given L as the length of a rectangle and W as its width, the area is calculated as:
A = L.W
Bob's swimming pool has L = w + 14 and a width of W = w + 8. Additionally, there is a walkway around the pool 4 feet wide. This walkway adds 2*4=8 to each dimension, thus: L = w + 22, W = w + 16.
Calculating the area:
A = (w + 22)(w + 16)
Operating:
![A = w^2 + 38w + 352](https://tex.z-dn.net/?f=A%20%3D%20w%5E2%20%2B%2038w%20%2B%20352)
Answer:
if I am correct 2/3 is bigger than 0.65
and I think 5.5 is smaller than 5 3/7
and I think the order goes 3/8 5/6 1/2
Answer: 44%
Step-by-step explanation:
There are other ways of doing this but here's how I did it:
Starting with an arbitrary price for the shirt of $100, I took 30% off and arrived at $70.
Then 20% off $70 is $56 (20% is one-fifth, so divide 70 by 5 and you get 14. Subtract 14 from 70 and you get 56.
Now subtract 56 from 100 and you get 44, so to get to 56 from 100 you subtract 44%.
You could also use a calculator or google it but that would be missing the point of studying math and benefiting from its practical applications, e.g., how to figure things out for yourself. And that wouldn't be much fun, would it?
