Answer:
The answer to your question is below
Step-by-step explanation:
Part A.
-3x + 7y = 13
Solve the equation for "y"
7y = 3x + 13
y = 
Part B.
Two lines are parallel if their slopes are the same
Two lines are perpendicular if their slope are opposite reciprocals
Slope of the first line = 
Slope of the second line =
Conclusion: the lines are parallel because their slopes are the same.
You would be able to fit 432 characters per yard. (12 x 32)
1. a= 60 (vertically opposite angles)
b= 360-(60+60)=240/2= 120 (angles at a point)
c= 120 (vertically opposite angles with b)
2. c= 90-40= 50 (vertically opposite angles)
b=a=360-90-90=180/2=90 (angles at a point)
3. a= 180-52-51= 77 (angles on a straight line)
b=52 (angles at a point)
d=51 (angles at a point)
c=77 (angles at a point)
4. a= 60 (vertically opposite angles)
b= 360-(60+60)=240/2= 120 (angles at a point)
c= 120 (vertically opposite angles with b)
e=65
d=f= 360-65-65=230/2=115
h=55
i=g=360-55-55=250/2=125
5. b=163
a=90
e=70
d=360-70-70=220/2=110
c=360-163-163=34/2=17
Hope this helps!
Answer:
6468
Step-by-step explanation:
6468 is equivalent to 1617
because 64 x 17 = 1088 and
68 x 16 = 1088.
The answer is 360 million or 720 million cells after 4 hours of doubling.
