David is making his own strawberry yogurt. In his mixture, the number of strawberries is proportional to the amount of milk in c

ratelena [41]

To determine the amount of milk that David should be adding, we need to generate and expression that would relate the number of strawberries and the number of cups. From the problem statement, it is said that the number of strawberries is directly proportional to the number of cups of milk. We write it as:

X α Y where X represents the number of strawberries and Y represents the number of cups of milk

To get rid of the proportionality sign, we introduce a proportionality constant k. We calculate this by using the initial conditions given.

X = kY

at X = 14 strawberries Y = 2 1/2 cups of milk = 5/2 cups
14 = k(5/2)
k = 28/5

At X = 203

X = kY
203 = 28/5 (Y)
Y = 145/4 or 36 1/4 cups of milk needed

How do you factor this? 2z^2-12z+10=0

kotykmax [81]

Answer:

This can't be factored right now! But if it is 2z^2+12z+10=0 than it will be factored like this:

2*(z+5)(z+1)

Step-by-step explanation:

2*(z^2+6z+5)=0

2*(z+5)(z+1)
