This would be 2 and 12/17
Answer:
She ordered 11 things
Step-by-step explanation:
you should have added the cost of each item then I could have given you the whole answer
-------------------
<span>x + 8 + 7 =7
x + 8 = 0
x = -8
</span>-------------------
Let x be the number of treats bought
Let y be the pounds of food bought
25= 2y+x
Given that she has buys 9 pounds of dog food:
25= 2(9)+x
25=18 +x
25-18 =x
7=x
With the money she has left over, she can buy 7 treats.
Hope I helped :)
=x2+2xy+3xy+6y2
=x(x+2y) +3y(x+2y)
=(x+2y)(x+3y)
