Answer:
46.2
Step-by-step explanation:
If you divide 231 by 5 then you get that answer.
Answer:
3
Step-by-step explanation:
P is the in-center
⇒PA=PE=PD because they are in-radius of the in-circle
We know that, tangent segments drawn from a point outside the circle are always equal in length
⇒DK=EK=7.2
In right triangle PKE,
using Pythagoras' Theorem : 
⇒
⇒
⇒
⇒
Therefore, 
Y = -x + 4.....so sub in -x + 4 in for y in the other equation
x + 2y = -8
x + 2(-x + 4) = -8
x - 2x + 8 = -8
x - 2x = -8 - 8
-x = -16
x = 16
y = -x + 4
y = -16 + 4
y = - 12
one solution (16,-12)
12s, you don’t have a value for s, so the problem can’t be fully solved but if you did you would multiply 12 by her speed
Hope this helps
Answer:
Step-by-step explanation:
-3x +12 =x-4
+3x
12 = 4x -4
+4
16 = 4x
Divide by 4
4 = x
