Answer:
Step-by-step explanation:
Let b represent the number of cups of butter needed.
Let s represent the number of cups of sugar needed.
Let o represent the number of cups of oat needed.
Let f represent the number of cups of flour needed.
The recipe calls for two times as many cups of sugar as butter. It means that
s = 2b
Two times as many cups of oats as sugar. It means that
o = 2s
Two times as many cups of flour as oats. It means that
f = 2o
If Duane puts in one cup of butter, it means that b = 1
Therefore,
s = 2 × 1 = 2 cups
o = 2s = 2 × 2 = 4 cups
f = 2o = 2 × 4 = 8 cups
Therefore, he needs to add 8 cups of flour
Answer:
The answer to your question is 
Step-by-step explanation:
Process
1.- Get to points of the line
A (-2, 0)
B (0, -1)
2.- Find the slope of the line
Slope = m = 
Substitution
m = 
3.- Find the equation of the line
y - y1 = m(x - x1)
Substitution
y - 0 = -1/2(x + 2)
Simplification
y = -1/2x - 1
Answer:
c
Step-by-step explanation:
the equation would be C because
A would end up with a negative amount
B is more than she originally has to paint and
D has the wrong coefficient for <em> t</em>.
