He can't write the equation because slope can't pass through x=3 twice.
In this case, (3,4) and (3,0). There can't be two exact same value in a slope.
12 cups of flour is 4 times the quantity in the recipe, so 4 times as much brown sugar is needed, 4×2=8 cups of brown sugar.
r and 5 both make 197
r would be a use of a number that isn't known unless you rearrange the equation
The equation would be 5r = 197 or 5 x r = 197
So you could make r the subject,
And to find it, you could divide 197 by 5
197 / 5 = r
Which then would make r = 39.4
Answer:
9.99
Step-by-step explanation:
If it is .18x then x equals 22,222.2222222222
If just 18 then x equals 222.222222
