This is your perfect answer
B. 6/9 because 6/9 equal to 2/3 so it’s basically the same ratio
Answer:
5/6=10/12. 2/4=6/12. 5/12
5/12. 2/4. 5/6
Answer:
1) B- Substitution
2) C- Elimination
3) A- Graphing
Step-by-step explanation:
1)
x+3y=7
5x+11y=3
x = 7 - 3y
Plug this x into the second equation and solve for y first
2)
5x-3y=3 --> (1)
2x+7y=6 --> (2)
Since making any variable the subject would involve fractions, it's better to go for elimination
7(1) + 3(2)
would eliminate y
3)
While comparing cost and adjusting choices, a graph is a better approach because all the possibilities are right in front
