Question

Help, me at this :) and ty

Answer 1

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
