Question

1) In a women's softball league, there are A-teams and B-teams. The total number of teams is 15. There are 15 women on an A-team and 16 women on a B-team. A total of 234 women play in the league. Write a system to solve the situation. Do not solve the system

.

Group of answer choices

A + 16B = 15

A + 15B = 234

A + B = 15

A - B = 234

15A + 16B = 15

A + B = 234

A + B = 15

15A + 16B = 234

2)Solve the system.

3x - 4y = -24

x + y = -1

5) The sum of two numbers is 78. Their difference is 34. Write a system of equations that describes the situation. Then, solve the system.

 

Group of answer choices

x + y = 78

x - y = 34

56 and 22

x - y = 78

x + y = 34

55 and 23

x + y = 78

x - y = 34

51 and 17



x + y = 34

y - x = 78

51 and 23

Answer 1

I will do the first one for you.

Then you should work the others and ask a specific question in a comment if you get stuck.

If you cannot do any of them, then you need a tutoring session, not answers to this question.

A+B=15

15A + 16B =234
