Answer:
I think it is 3.
Have a nice day :3
Step-by-step explanation:
13. 8d - 10 = 4(2d - 6)
8d - 10 = 8d - 12
8d - 8d = -12 + 10
0 = -2......incorrect....NO SOLUTIONS
14. 3.50c > = 500
c > = 500/3.50
c > = 142.857....she can sell (minimum) of 143
15. 14c - 10 = 20
14c = 20 + 10
14c = 30
c = 30/14 reduces to 15/7 (or 2 1/7)
16. c = 1.50g + 3
-x+2y
You have 3x+y and you need to make it 2x+3y
The difference between 3x and 2x is 1x(x)
And the difference between y and 3y is 2y
For the x you have to minus x from 3x to get 2x,(3x-x=2x)
For the y you have to add 2y to y to get 3y,(y+2y=3y)
Now add them
=3x+y+-x+2y=2x+3y
Therefore you add -x+2y
You have to give us the options for the question..... not just the question.
