Let x= number of avocadoes she can buy
let y= total cost
y= 2x
9= 2x 9/2= 4.5
4.5= x
(you cannot cut the avocado in half therefore your answer is simply 4)
The answer is C. Hope this helps
3x + 3 = -2x + 2 - 4
3x + 3 = -2x - 2
Add 2 to each side
3x + 5 = -2x
Subtract -3x from both sides
5 = -5x
Divide each side by 5
1 = -x
Since you can leave x negative you reverse it with 1 and your answer will be >>> x = -1
Answer:
-3x-7
Step-by-step explanation:
-3x and -6 aren't like terms, and neither are -3x and -1, so you leave -3x alone. You can combine -6 and -1. You simply add them as if they aren't negative and keep the negative sign. This results in -3x-7
