A package of hotdogs contains 10 hot dogs. A package of buns contains 8 buns. What is the least number packages of buns and hot dogs you must purchase, so you won't have left over hot dogs?
2 answers:
10 = 5 x 2
8 = 2 x 2 x 2
The LCM OF 8 and 10 = 2 x 2 x 2 x 5 = 40
Therefore to find out how many packages of hot dogs you would have to buy you would do 40 ÷ 10 = 4.
To find out how many packages of buns you would have to buy you would do 40 ÷ 8 = 5.
So you would need 4 packages of hot dogs and 5 packages of buns.
Hope this helps :)

Answer:
y = -0.5x + 2
Explanation:
2x + 4y = 8
Add -2x to both sides
2x + 4y + −2x = 8 + −2x
4y = −2x + 8
Divide both sides by 4
4y / 4 = -2x + 8 / 4
y = -1/2x + 2
-1 ÷ 2 = -0.5
y = -0.5x + 2
None. The triangle inequality states that the sum of the smaller two sides of a triangle must be greater than the third side. As 4+5=9, this inequality is false in this case, so these sides cannot create a triangle.
