Step-by-step explanation:
8) u = vw + z
For v,
u = vw + z
u - z = vw
(u - z)/w = v
v = (u - z)/w
9) x = b - cd
For c,
x = b - cd
x - b = -cd
-(x - b)/d = c
c = -(x - b)/d
= (-x + b)/d
OR
x = b - cd
cd = b - x
c = (b - x)/d
10) fg - 9h = 10j
For g,
fg - 9h = 10j
fg = 10j + 9h
g = (10j + 9h)/f
11) 10m - p = -n
For m,
10m - p = -n
10m = -n + p
m = (-n +p)/10
12) r = (2/3)t + v
For t,
r = (2/3)t + v
r = 2t/3 +v
r - v = 2t/3
3(r - v) = 2t
t = 3(r - v)/2
13) (5/9) v + w = z
For v,
5v/9 + w = z
5v/9 = z - w
5v = 9(z - w)
v = 9(z - w)/5
14) (10ac - x)/11 = -3
For a,
(10ac - x)/11 = -3
10ac - x = -3 × 11
10ac - x = -33
10ac = x - 33
a = (x - 33)/10c
15) (df + 10)/6 = g
For f,
(df + 10)/6 = g
df + 10 = 6g
df = 6g - 10
f = (6g - 10)/d
Answer:
The diameter is any straight line that passes through the center of the circle, which endpoints can lie on. The radius is half the diameter. They help us find the circumference of a circle
Answer:
<em>I</em><em> </em><em>think</em><em> option</em><em> A</em><em> </em><em>is</em><em> right</em><em> answer</em>
The first two pieces are the same, let each of those equal x, so you have x + x = 2x
The 3rd piece is the sum of the first two + 4, so this would be 2x + 4
Now you have 2x + 2x + 4 = 100 cm
Combine like terms:
4x +4 = 100
Subtract 4 from both sides
4x = 96
Divide both sides by 4
X = 24
First piece is 24 cm
Second piece is 24 cm
Third piece is 52 cm
