Answer:

y=2.5

Step-by-step explanation:

first you add -3x to both sides so you get 5-3x and then divide that by 2 to get Y by itself so now you have 5/2 - 3/2x and when you put in the equation y=5/2 - 3/2x in DESMOS, the answer is 2.5

a chef uses 4 3/4 cups of broth for 10 servings of soup. How much broth is used in one serving of soup?

mafiozo [28]

Set up a proportion. 4 3/4 cup broth is to 10 servings as x cups broth is to 1 serving soup.

x= amount of broth in one serving

(4 3/4)/10= x/1
cross multiply

(4 3/4)(1)= 10x
convert 4 3/4 to improper fraction

(19/4)(1)= 10x

19/4= 10x
divide both sides by 10

19/4 ÷ 10= x
to divide fractions, multiply by reciprocal of 10

19/4 * 1/10= x
multiply numerators; multiply denominators

(19*1)/(4*10)= x

19/40 cup= x

ANSWER: 19/40 cup in one serving

Hope this helps! :)
