16 1/2 cup servings if they are putting the grape juice and the lemonade together then that adds up to be 8 and then you have to fine how many 1/2 cups you can get out of 8 which is going to be twice as much so it's 16
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
First you add 3 and 2 so that is 5 and then you subtract 5 from 9 so the answer is 4.
Product means multiply, a number means any variable so 6x is the answer
Answer:
9
Step-by-step explanation:
30 - (9+4 x 3)
30 - (9 + 12)
