3x+2y= -8
multiply by 3 to,x-y= -1
so u will get,
3x+2y= -8
-3x+3y=+3,eliminating both of them you will get,
5y= -5
y = -1
by applying the value of y,
3x+2*-1= -8
3x - 2= -8
3x= -5
x = -5/3
Answer: probability for 1st marble being green is 2/9 and 2nd marble being red is 1/4
Step-by-step explanation:
I hope this is correct. since there are 9 marbles and 2 of them are green, you do 2/9 which is 2/9 in its simplest form. And since you didn't put back the first marble there are 8 marbles left and 2 of them are red. You do 2/8 which in its simplest form is 1/4. I hope this helps
Answer:
2x/2+1/2
x=1/2
Step-by-step explanation:
Answer:the linear equation for the fundraising goal is 8x + 12y = 240
Step-by-step explanation:
Let x represent the number of water bottles that the Environmental Club would sell.
Let x represent the number of tote bags that the Environmental Club would sell.
The Environmental Club is selling water bottles for $8 and tote bags for $12 to raise $240 to donate to charity. This means that
