Answer:Domestic Stamps: 123
Foreign Stamps: 89
Step-by-step explanation:
So we have two equations
x - y = 34
x + y =212
Let's take the first equation and put it in terms of x
x-y+y= 34+y
x= 34 + y
Now that we have a value for x, substitute it into the second equation for x and solve for y.
(34+y)+y=212
34+y+y = 212
34+2y= 212
34-34+ 2y=212-34
2y= 178
2y/2=178/2
y= 89
Now that we know the value for y, we can substitute it into the first equation and solve for x.
x-89=34
X-89+89=34+89
X=123
Y= 89
X =123
ANSWER
Domestic Stamps: 123
Foreign Stamps: 89
Answer:
x=-4 or x=-1/2=-0.500
Step-by-step explanation:
Remmeber that an octagon is a polygon formed by chain of 8 straight line segments.
The first valid name for a polygon of eight sides is octagon (from greek oktagonon, which means eight angles)
The second valid name for a polygon of eight sides is eight-sided polygon.
The third valid name of a polygon of eight sides is 8-gon. After 6 sides, mathematicians usually refer to these polygons as n-gons, so an eight-sided polygon will be an 8-gon.
We can conclude that the three valid names for an octagon are: octagon, eight-sided polygon, and 8-gon.
Answer:
6 divided by 6 would be 0:
7/0 = 7
Your answer is 7
Answer:
y=-2x+1
Step-by-step explanation:
to find the slope use the formula (y2-y1)/(x2-x1)
-5-3= -8
3-(-1) = 4
-8/4 = -2
