Activity 2. Solve for the unknown.
1. If x varies jointly as y and z and x = 12 when y = 1 and z = 6, find x when y = 6 and z= 10.
2. If z varies jointly as x and y and if z = I when y = 2 and x = -3, find x when z=2 and y = 4 y
3. If x varies directly as y and inversely as z, and if x = 30 when y = 2 and z 3, find y = 2 = 15 and x = 30. 3

so hard Let me Know Wait....
10=k(2)(5)
10/10=10k/10
k=1
z=(1)(6)(12)
z=72
2.z=kxy
2=k(6)(4)
2/24=24k/24
k=1/12
4=(1/12)(x)(8)
4=2/3x
4/3/2=x
x=6

(30x40)/80 = (X2 x24)/40
X2 = [(30) (40) (40) ] / [(80) ((24)
X2 = 25
