Solve 5kx + 6 = 7kx for x
ad-work [718]
Right now we have: 
5kx + 6 = 7kx 
First, divide both sides by k to eliminate that variable:
5x + 6 = 7x
Then subtract 5x from each side:
6 = 2x
Lastly, divide each side by 2 to solve for x: 
3 = x
Hope this helps!

All of the ingredients are purchased in bulk sizes. The butter comes in 12-cup containers. How many recipes will each container
Citrus2011 [14]

Answer:

some information is missing, so I looked for similar questions and found the attached image:

since each recipe requires ¹/₂ cup of butter, you are able to make 12 ÷ ¹/₂ = 24 recipes with one container of butter (assuming you have all the other ingredients).

One-half, ¹/₂, is a fraction that can also be written in decimal form as 0.5. Two times ¹/₂ is equal to 1, and similarly, twenty four times ¹/₂ is equal to 12.
