Answer:
10 1/12
Step-by-step explanation:
In order to subtract fractions, you have to give them a common denominator.
18 1/2 can be rewritten as 18 6/12, as they are the same thing and 6/12 simplifies to 1/2. We make it 6/12 because we have to subtract it by 8 5/12, and the denominators are both 12.
So now we have 18 6/12 - 8 5/12, which gives us 10 1/12.
(x + 7) - (3x + 4)=
x + 7 - 3x - 4 =
-2x + 3
Answer:
24
Step-by-step explanation:
The cake measures 10 inches by 15 inches. If pieces are 2.5 inches long and wide (they are square and equal) then 6 pieces will be cut along the length.
15/ 2.5 = 6
And 4 pieces will be cut along the width.
10/ 2.5 = 4
All together when the entire cake is cut, there will be 4*6 = 24 squares 2.5 inch long pieces.
