Answer: x= 37
Step-by-step explanation:
Answer:
x=16
y=23
Step-by-step explanation:
angle (4x+4) and angle (7x-44) are alternate exterior angles which are equal, so we can set up an equation like this to find x:
4x+4=7x−44
calculate it then you'll get x=16
for the next one I'm not really sure how to explain since they are not labeled but,.. since we have the measure 39 we can figure out by using the pairs 'interior angles on the same side of a transversal' and 'vertical angles' that it's equal to 141, so to find y we use the equation
8y-43=141
calculate it and you'll get y=23

To take a systematic sample, first choose any number between one and five and write it here: k-23
Using the atomic number to count off elements, let the k value you just chose represent the first element in your
sample. Then, count off every fifth element thereafter. For instance, if you chose k-2, your sample will include
Helium (2), Nitrogen (7), Magnesium (12), and so forth. List each atomic number and atomic weight, starting with k
and adding 5 to the atomic number cach time.
