2l + 2w = p
If you already have perimeter and length, you can use this formula to solve for width.
Answer option D
Step-by-step explanation:
1) m=8d $40
2) d=15h 45 mi
3) less than one hour
3x - 4 + 1 = -2x - 5 + 5x
First, simplify 3x - 4 + 1 to 3x - 3. / Your problem should look like: 3x - 3 = -3x - 5 + 5x
Second, simplify -2x - 5 + 5x to 3x - 5. / Your problem should look like: 3x - 3 = 3x - 5
Third, cancel 3x on both sides. / Your problem should look like: -3 = -5
Fourth, since -3 = -5 is false, there is no solution.
Answer: No solution
