Let's look at an example:
2.24 x 21.6

Do normal multiplication and get
48384 This is not correct, until we put the decimals in. To know how to do this, count the number of decimal spaces from the factors. In 2.24, there are 2, because .24. In 21.6 there are 1 because of .6. This mean three places, so 48384 becomes
48.384

Answer:
Step-by-step explanation:
x + 29 + 12 = 89
x + 41 = 89
x = 48 for <CED
2(area of s) + 2(area of f) + 2(area of ff) if s = side and f= opposite faces and ff = opposite faces.
2(4x3) + 2(3x10) + 2(4x10)=
24+60+80=
164 in squared
Answer:
- Blueberry pie costs $9, lemon meringue cost $14
Step-by-step explanation:
<u>Set equations:</u>
- 13x + 12y = 285
- 3x + 12y = 195
<u>Solve by elimination. Subtract the second equation from the first:</u>
- 13x + 12y - 3x - 12y = 285 - 195
- 10x = 90
- x = 9
<u>Find the value of y:</u>
- 3*9 + 12y = 195
- 12y = 195 - 27
- 12y = 168
- y = 168/12
- y = 14
