Hi, My scribe today is about that sheet that Mr . Harbeck told us to answer. The sheet I got was page 48 so if my questions are different than yours... too bad.
1. Enigma is __57___ old
Let x = age
- 1/3 x - 5 = 14
- x/3 - 5 = 14 + 5
- x = 19 x 3
- x= 57
- x/3 - 5 = 14
- 57/3 - 5 = 14
- 14 = 14
3. She rented ___26___ movies
Let x = movies
- 3x + 12 = 90
- 3x + 12 = 90 - 12
- x = 78/3
- x = 26
- 3x - 12 = 90
- 3(26) + 12 = 90
- 90 = 90
6. He ate ___22___ Chips
Let x = Chips
- 12x + 375 = 639
- 12x + 375 = 639 - 375
- x = 264/12
- x = 22
- 12x + 375 = 639
- 12(22) + 375 = 639
- 639 = 639
8. It took __13 _ Min.
Let x = minutes
- 25x + 75 = 400
- 25x + 75 = 400 - 75
- x = 375/26
- x = 13
- 25x + 75 = 400
- 25 (13) + 75 = 400
- 400 = 400
9. They need ___10800 wrapping paper
Let x = Wrapping paper
- 1/2 x - 400 = 5000
- x/2 - 400 = 5000 + 400
- x = 4600 x 2
- x = 10800
- x/2 - 400 = 5000
- 10800/2 - 400 = 5000
- 5000=5000
Just comment if i did something wrong. Thanks!
