The only possible methods for determining if the triangles are congruent is SAS, SSS, ASA, AAS, RHS

So you know what answers you can eliminate.

It tells you CA bisects angle BAD. "Bisect" means cut in half equally, so you know that angle CAB and angle CAD is the same. This is angle proof.

Something seems to be cut off from the picture. Depending on what it tells you (for example line xx = line xx), you can figure out the answer.

Answer:

  8. 8x +2.5

Step-by-step explanation:

7. The equation matches the pattern ...

  a(b + c) = ab + ac  . . . . . . .  statement of Distributive Property

with a=√2, b=5, c=4

__

8. The one-time charge of 2.50 will appear added in the equation one time (and not multiplied by anything). The number of tickets (x) will be multiplied by the ticket charge (8) and added to the one-time charge. Only one answer choice does that:

How would you go about finding the solution to this system of three equations in three variables? Be specific. For example, you
kupik [55]
I:2x – y + z = 7
II:x + 2y – 5z = -1
III:x – y = 6

you can first use III and substitute x or y to eliminate it in I and II (in this case x):
III: x=6+y
-> substitute x in I and II:
I': 2*(6+y)-y+z=7
12+2y-y+z=7
y+z=-5

II':(6+y)+2y-5z=-1
3y+6-5z=-1
3y-5z=-7

then you can subtract II' from 3*I' to eliminate y:
3*I'=3y+3z=-15

3*I'-II':
3y+3z-(3y-5z)=-15-(-7)
8z=-8
z=-1

insert z in II' to calculate y:
3y-5z=-7
3y+5=-7
3y=-12
y=-4

insert y into III to calculate x:
x-(-4)=6
x+4=6
x=2

so the solution is
x=2
y=-4
z=-1
