The equation to find the length of the longer piece is
x- 12 = 55
Step-by-step explanation:
- A carpenter had two pieces of lumber that totaled in length = 55 feet
- The shorter piece than the longer piece has length of which is = 12 feet
- The longer piece is denoted as= x
- Find x = ?
- The equation can be formed to find the value of x as,
- Longer piece (x) ₋ shorter piece (12) = total length (55)
- Therefore, x ₋ 12 = 55
- the above equation states that
- if you subtract the shorter piece from the total length of the you will get the length of the longer piece.
- therefore,
- if you shift the value of shorter length on the right hand side, you can find the value of x
- so, x= 55 ₋ 12
- value of x = 43
- therefore, the length of the longer piece is 43 feet long.
Well if u divide 100 by 20 you'll get 5 groups of cookies and brownies
