2x2-3x-20=0
4-3x-20=0
2-20=-16
-3x-16=0
-3x=16
x= -5.33333
I think i did it right. i hope this helps.
Your answer would most likely be 1/2 (open the image for your steps )
But if you're looking for the decimal of this problem it would be: 0.5
✌️Good luck on your assignment ✌️
Answer:
7
Step-by-step explanation:
So, we know that this process happened 3 times in total. The original amount of kids we can call x, so the next wave filled in the gaps inbetween, so we call that amount x-1, the next wave would be (x+x-1)-1 or 2x-2, and the last would be 4x-4
adding this all up we get 8x-7=49, so 8x = 56 or x = 7
Because tens numbers are easier to work with. If you have the problem 9+3, you can take one out of three and add it to the nine to get 10+2.
