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.
- 15= 5d
- 15 = 3d
- 15 =d
- 15 =2d
The correct answer is: 15 = 3d
we are asked to write an equation that says that the length of the green line is equal to the length of the black line.
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 15.
The black line is the sum of its segments, so:
length of black line = d + d + d
= 3d
Putting these together gives:
15 = 3d
Thus we find that the solution to the problem is choice 2
