v = w - 20
move -20 to the other side
sign changes from -20 to +20
to get w by itself
v+20= w-20+20
Answer:
w= v+20 or w= 20+v
6 - 1/2z = 2/3
subtract 6 from both sides
- 1/2z = -16/3
divide both sides by -1
1/2z = 16/3
rewrite
1z/2 = 16/3
multiply both sides by 2
1z = 32/3
z = 32/3 or 10 2/3
Hope this helps :)
Answer: See below
Step-by-step explanation:
Triangle ABC has vertices located at A( 0, 2), B (2, 5), and C (−1, 7)
A)
B) Slope of AB line = m₁=3/2
Slope of BC line = m₂=-2/3
Slope of CA line = m₃=-5
C) 
Therefore, the triangle is a isosceles right angle triangle
It actually depends on a.
A might be rational.
Answer:
the play area is a circle with radius = 12
Step-by-step explanation:
Circle area = A= π r²
r = radius
A = 144 π = 452.39
Diameter = 2r
= 24
circumference = C = 2π r
= 24 π = 75.4
Q2)
Area = π r²
r = 15
r²= 225
area = 706.5
