Answer:
x=-4
y=-4
Step-by-step explanation:
We are going to eliminate the variable x. In order to do this, we are going to make the coefficients the same by multiplying the second equation by 2

Step-by-step explanation:
Total amount of apples in one bag:

Hence, total amount of apples in two bags:

or

or 

Hence, B, D and E are correct.
A is incorrect because you are adding 2 more apples on top of the total amount of apples in one bag, and you cannot assume that there are 2 apples in each bag.
C is incorrect because you are multiplying the apples together, but you are supposed to add them up to find the total.
F is incorrect because you are finding 1/2 a bag.
 
        
             
        
        
        
X=9
DBC= 54°
The given angle is 90°, so we can add the other two given equations to equal 90.
7x-9+4x=90
1) Combine like terms
11x-9=90
2) Add 9 to both sides
11x=99
3) Divide 11 on both sides
x=9
Now to find the angle:
7x-9
1) Plug 9 in for x (which is what we just solved for)
7(9)-9
2) multiply
63-9
3) subtract
