Switch the parts on the right where it says “Multiplication property” and “subtraction property”
You need to find out how many problems Carl can do in a minute (unit rate), which is 20/55 or .36363636363. If you multiply it by 75 mins, you get 27.27, so the answer would be 27.
If the baker made 5 pounds of icing and used 4/9 of the icing to make decorations, then he used:
5 * 4/9 =
= 20/9 =
= 2 2/9 [of icing]
To find out how much he has left over, we just need to substract 2 2/9 from 5:
5 - 2 2/9 =
= 3 - 2/9 =
= 2 7/9
Answer: The baker has <u>2 7/9</u> of the icing left.
6x + 2x - 1 = 5x + 11
8x - 1 = 5x + 11
- 5x - 5x
3x - 1 = 11
+ 1 + 1
3x = 12
3 3
x = 4
