The answer is 1/7n + 32/21
Ok, so there are 2 men per 7 women so we can just scale up so there are 4 men per 14 women and then 6 men per 21 women but there are 36 performers so we have to keep going till it equals 36 people so 8 men per 28 women = 36 people so 8 men!
Let s be the cost of one shirt and t, the cost of 1 tie
Then:
(a) 3.s + 5.t = 60
(b) 2.s + 3.t = 39
Solve this equation by elimination:
<span> Let's eliminate t. To that end you multiply all the terms of (a) by negative 3 and all the terms of (b) by positive 5
</span>(a) 3.s + 5.t = 60→→ (-3).(3.s+5.t) → - 9.s - 15.t = -180(c)
(b) 2.s + 3.t = 39→→ (+5).(2.s+3.t) → +10.s + 15.t = 195 (d)
Now you add (c) + (d) → s= $15 , This is the cost of 1 shirt. To find the cost of 1 tie, you replace s by 5 in any of the equation, say (b):
(b) <span>2.s + 3.t = 39 </span>→ 2.(15) + 3t = 39 → 30+3t = 39 and 3t =39-30 = 9
So 3t = 9 and t = $3 (price of 1 tie)
I think you're answer is five hundred seventy six
The answer is 218’. A foot front is measured by property. So for this question, you need to find the frontage feet.
