Answer:
1/2 cup of milk
Step-by-step explanation:
Given
Total cup of milk needed = 3/4 cup of milk
Amount she has = 1/4 cup of milk
The amount of milk she needed = Total - Amount she has
Amount she needed = 3/4 - 1/4
Amount she needed = (3-1)/4
Amount she needed = 2/4
Amount she needed = 1/2
Hence she needs 1/2 cup of milk more
I think y = 8. Since x = -3 then the equation would be y = -1(-3) +5. -1 times -3 equals 3. So now the equation is y = 3 +5. That would give you 8.
The answer would be the first choice. 
Explanation: The reason for this is that the question was pretty much just asking what the area of the resulting two-dimensional cross section would be -the shape in gray- (which can be found by using the formula
. To add on, since the dimensions of the shape are already given (5 and 3) all you've to do is multiply: 3*5=15
That's how you get to the answer.
