Need the setup info to verify whether the proportion is set up correctly. Solution of this proportion:
x = (6 x 5)/4, so
x = 7.5
Joelle set up the following proportion: 4/6 = 5/x. Solve for x.
Determine if proportion is correct. If not, explain what is wrong with it.

BD = 4
DA = 5
DE = 6
Solving for x
1. Joelle’s proportion is correct.
2. Joelle’s proportion is not correct because BD, which is 4, corresponds proportionally to BA, which is 9, not 5.
3. Joelle’s proportion is not correct because DE, which is 6, does not correspond proportionally to AC, which is x.
4. Joelle’s proportion is not correct because DE, which is 6, corresponds proportionally to BA, which is x + 6, not x.
DA = 5
DE = 6
Solving for x
1. Joelle’s proportion is correct.
2. Joelle’s proportion is not correct because BD, which is 4, corresponds proportionally to BA, which is 9, not 5.
3. Joelle’s proportion is not correct because DE, which is 6, does not correspond proportionally to AC, which is x.
4. Joelle’s proportion is not correct because DE, which is 6, corresponds proportionally to BA, which is x + 6, not x.
