Answers

Answer 1

Answer:

x = $(5)/(26)$

Step-by-step explanation:

Given equation:

$(3)/(4)x + (5)/(8) = 4x$

$(3(2)x + 5)/(8) = 4x$ ∵taking GCF 8

$(8 (6x + 5) )/(8)$ = 4x × 8

6x + 5 = 32x ⇒ 5 = 32x - 6x ⇒ 5 = 26x ⇒ x = $(5)/(26)$

A recipe for pudding call for 2 1\2 of milk. the recipe make 5 servings . how many cups of milk are needed to make 8 servings

Answers

8 servings* (2 1/2 cups of milk/ 5 servings)= 4 cups of milk.

The final answer is 4 cups of milk.

Hope this helps~

I think the amount of cups needed are 16.8 because if you set up the problem (but simplify the fraction into a decimal first) you set it up as 10.5/5=x/8 then you cross multiply 10.5*8(times) and get 84, last you divide by 8 and you get 16.8. I don't know what that is as a mixed number but I'm sure you can figure it out.
