The answer: d. < 1 and < 8
You first want to make an equation for the problem. Let x be the number of teams needed since the problem doesn’t include it.
30=5x
Divide 5 by both sides to get x on its own side
*What you do to one side you do to the other
30/5=5x/5
6=x
A half times a half is a quarter. You can think of it this way: 1/2 is equivalent to 0.5, so you do 0.5 times 0.5 which is 0.25.(answer)
So, the problem is asking for one of the equations to be rewritten. Lets rewrite the second one. The way to create a system of equations that will cancel is to create a situation where the a or b of both equations add to 0. In this case, we can multiply the second equation by 3 to turn the 3y into 9y.


Our new system is
and
. We can now add these together.


Adding each part straight down, we get the equation:

We now have an equation with a single variable, which also tells us that x is equal to 27.
Extra: To find the value of y after this, we merely need to plug in the value of x to one of the equations and solve for y.



Answer:
That's strange. (-1/2, 5) would work for both if only the top equation had a less than or equal to sign. If all else fails, just puts c as your answer lol
