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.
20x + 5y = 15
Subtract 20x on both sides
5y = 15 - 20x
Divide by 5 on both sides
y = 3 - 4x
they are parallel to each other so find it out from there

Answer:
- 3n+6 (n = smallest)
- 3n (n = middle)
Step-by-step explanation:
The usual method for doing this is to let n represent the smallest one. Then the three integers are ...
n, n+2, and n+4
and their sum is ...
(n) +(n+2) +(n+4) = 3n+6 . . . . sum of 3 consecutive odd integers (n = smallest)
_____
Personally, for consecutive number problems, I prefer to let the variable represent the average value. If n is the average value of 3 consecutive odd integers, is is the middle integer. Of course, the sum will be 3 times the average:
(n-2) +(n) +(n+2) = 3n . . . . sum of 3 consecutive odd integers (n = middle one)
X, x+2, and x+4 are the numbers where x=odd integer
x+(x+2)+(x+4)=51
3x+6=51
3x=51-6
3x=45
x=45/3
x=15, x+2=17, x+4=19
also you can do the following...
51/3=17
17-2=15
and 17+2=19
