Answer:
9
Step-by-step explanation:
Yes it is (10x-y)^2 is the answer of it
-7=z/2+1
What you first need to do is to multiply both sides of the equation by 2
-14=z+2
Now you move the variable to the left side and change within it’s own sign
-z-14=2
Into
-z=2+14
Now you then add the numbers
-z=16
The last part you do is change the sign on both sides in this equation
z=-16
Therefore, z=-16 is your answer in number 16.
Where’s the image? There has to be an image showing the angles to see which pairs of angles are supplementary.
