The GCF is 2
Pull out 2 from each number:
2(2n + 5)
Hope this helps!
First, use distributive property on the right half.
2 * 5 = 10
2 * 2n = 4n
4n - 9 = 10 + 4n
Add 9 to both sides
4n = 19 + 4n
Subtract 4n from both sides
0 = 19
But thats not true. Therefore, there is no solution.
Answer:
with proportional relationships, you can simply divide the y coordinate by the x coordinate to find the unit rate: In this case, if (5,4) lies on the line then you have 5 lbs of potatoes for 4 dollars or .80 cents for 1lb of potatoes. The point (10,8) represents 10 lbs of potatoes for 8 dollars. Here you can see that dividing 8 by 10 we once again get the unit rate of .80 cents per 1 lb of potatoes.
x = lbs of potatoes and y = price(4,3)....this means 4 lbs of potatoes cost $ 33/4 = 0.75 cents per lb <== 1 lb of potatoes cost 0.75(8,6)...this means that 8 lbs of potatoes cost $ 6
