59 is the answer all you do is add 14 to 45 and you'll get t9
You need to solve the equation for h.
<span>W= 50+2.3(h-60)
Distribute the 2.3.
W = 50 + 2.3h - 138
W = 2.3h - 88
Add 88 to both sides.
W + 88 = 2.3h
Switch sides.
2.3h = W + 88
Divide both sides by 2.3.
h = (W + 88)/2.3

thank you your welcome lol
One of the approaches:
Each couple can send only one "representative" to the committee. Let's see in how many ways we can choose 3 couples (as there should be 3 members) out of 4 to send only one "representatives" to the committee: 4C3=4.
But each of these 3 couples can send two persons (husband or wife): 2*2*2=2^3=8.
Total # of ways: 4C3*2^3=32.
hope it helped a bit
