Step-by-step explanation:
proportion time...
3 teaspoons salt to 4 cups flour = x teaspoons salt to 28 cups flour
3 x
----- = ----- cross multiply
4 28
(4)(x) = (3)(28)
4x = 84
x = 84/4
x = 21 <==== 21 teaspoons of salt are needed

Answer:
x = 5 when y = 12
Step-by-step explanation:
If y is inversely proportional to x, we can say that x1 : x2 = y2 : y1
The order of y2 and y1 respectively are interchanged as y is inversely proportional to x
Now let us simply substitute our known values, and solve for x2;
x1 : x2 = y2 : y1
20 : x2 = 12 : 3
20/x2 = 12/3
12(x2) = 3(20)
12(x2) = 60
x2 = 60/12 = 5
Since it’s not x3 it must be +8 so if i were you i’d pick B
