Question
Write an equation that says that the length of the green line is equal to the length of the black line. Combine like terms.
- 27 = 3n
- 27 = n
- 27 =2n
- 27 =5n
Hint:
Finding an equation that says that the length of the green line is equal to the length of the black line.
length of green line = length of black line
The length of the green line is 27.
The black line is the sum of its segments
The correct answer is: 27 = 3n
We want to replace both sides of the equation below with numbers and variable expressions:
length of green line = length of black line
The length of the green line is 27.
The black line is the sum of its segments, so:
length of black line = n + 2 = 3n
Putting these together gives:
27 = 3n
