solve the following system of equations.
9x + 5y = -66
3x + y =-12
a. x = 5, y = -22.2
b. x = -15, y = 1
c. x = 1, y = -15
d. x = 12, y = -48

The classrooms are trying to raise $1,200.00 for charity. mrs. leblanc's class has raised 50%. mr. patel's class has raised $235.14 ms. warner's class has raised 1/3 as much as mrs. leblanc's class. how much more money is needed to reach the goal of $1,200.00?

When you answer this can you explain

If you can solve all of these i will give ! - 4% of 190 - 4% of 162.5 - 4% of 140 - a 4% increase from 155.1 - a 4% increase from 159.8
