Write and solve equations that represent diagrams
Learn with an example
🔔 Write an equation that says that the length of the green line is equal to the length of the black line.
Equation: _____
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 24.
The black line is the sum of its segments, so:
length of black line = h + 18
Putting these together gives:
24 = h + 18
🔔 Write an equation that says that the length of the green line is equal to the length of the black line.
Equation: ______
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 11.
The black line is the sum of its segments, so:
length of black line = p + 5
Putting these together gives:
11 = p + 5
🔔 Write an equation that says that the length of the green line is equal to the length of the black line.
Equation: _____
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 11.
The black line is the sum of its segments, so:
length of black line = p + 4
Putting these together gives:
11 = p + 4
