Answer:
x = 8 , x = - 2.5
Step-by-step explanation:
( x - 8 ) ( 2 x + 5 ) = 0
1. x - 8 = 0
2. 2 x + 5 = 0
x - 8 = 0
( + 8 on both sides )
x = 8
2. 2 x + 5 = 0
( - 5 from both sides )
2 x = - 5
( ÷ 5 on both sides )
x = - 2.5
Answer: the original length of the piece of wood is 23 feet
Step-by-step explanation:
Let x represent the original length of the piece of wood.
He cuts 3 feet off the piece of wood. This means that the remaining length of wood would be
(x - 3) feet
he cuts the remaining length of wood into four equal parts. if each part is 5 feet long, it means that
(x - 3)/4 = 5
Cross multiplying by 4, it becomes
x - 3 = 4 × 5
x - 3 = 20
x = 23
64-12= 52
So, she ate 52 since I subtracted what she had eaten (12) from how many she started (64)
So the answer would be 52
Don’t get mad at me if I’m wrong

Where does the 0 come into play? If it's just a random number move the decimal from the end of the number (0625.) in two places where it would be 06.25
