It's c. ZY have the same y and WX have the same y value. so they'll never touch
38 samples per hour is your answer
3p-4=8
+4 on both sides to get
3p=12
divide each side by 3 to get p=4
2p=4
divide off 2 on both sides to get
p=2
Is 2=4? If it is then it is equivelent, if it isnt then theyre not.
The angle addition postulates states that if an angle UVW has a point S lying in its interior, then the sum of angle UVS and angle SVW must equal angle UVW, or ?UVS + ?SVW= ?UVW.
(5-4)-3 = -2. If we move the parenthesis, as is defined by what the associative property is, 5-(4-3) = 4. No matter what, you always approach mathematical equations or expressions using PEMDA. We have to do what's inside the parenthesis first, which is why we end up with 2 different solutions using subtraction.
