<h3> Option (b)      x = \frac{15}{4}</h3>

Step-by-step explanation:

Using the property SSS

\frac{6}{6+x} =\frac{8}{8+5}

⇔\frac{6}{6+x} =\frac{8}{13}

⇔8(6+x) = 6 × 13

⇔48 + 8x =78

⇔ 8x = 78 - 48

⇔ 8x = 30

⇔x =\frac{30}{8}

⇔x = \frac{15}{4}

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.
