A recipe uses 7 parts of milk for every 5 parts of sugar how much sugar do you use when you use 28 cups of milk

the answer is 20 cups of sugar

Step-by-step explanation:

7/28= 5/x

x= 20.

x reps the number of cups of sugar

answer:

(-8,7)

explanation:

we know that  

f

(

−

3

)

=

7

therefore, if we wish to get the output as 7, in the function, we need to have our input to be -3.

looking at the function  

f

(

x

+

5

)

, what should the value of x be, such that the input in the function becomes 7?

we simply equate the terms,

x

+

5

=

−

3

x

=

−

8

thus, the point on the new function would be  

(

−

8

,

7

)

25% is the answer
