\dfrac{5}{2s} + \dfrac 3 4 = \dfrac{9}{2s}

Common denominator 4s, let's multiply through,

10 + 3s = 9

3s = -1

s = -1/3

Check:

5/(-2/3) + 3/4 = -15/2+3/4 = -27/4

9/4s = 9/(-4/3) = -27/4, good

Answer: s=-1/3

X + 9y = 8 x − 4y = –18
loris [4]

Step-by-step explanation:

x + 9y =  - 18 \\ 8x - 4y =  - 18 \\ x =  - 18 - 9y \\ 8( - 18 - 9y) - 4y =  - 18 \\  - 144 - 72y - 4y =  - 18 \\  - 76y = 126 \\ y =  - 1.66 \\

x =  - 18 - 9y \\ x =  - 18 - 9( - 1.66) \\ x =  - 18 + 14.94 \\ x =  - 3.06

An electronics company has developed a new hand held device. The company predicts that the start up cost to manufacture the new
alex41 [277]
Profit = revenue - expenses

expenses : 125,000 + 6.50x
revenue : 9x
so to make a profit, ur revenue (income) has to be higher then ur expenses

revenue > expenses
A. ) 9x > 125,000 + 6.50x
9x - 6.50x > 125,000
2.5x > 125,000
x > 125,000 / 2.5
x > 50,000......so they would have to sell at least 50,001 devices to make a profit <==

B.) the cost of making 1 device is 10% more then the company predicted....10% more then 6.50.....6.50(1.10) = 7.15.....this is the new cost of making 1 device <==

9x > 125,000 + 7.15x ....this is the inequality with the 10% more added
9x - 7.15x > 125,000
1.85x > 125,000
x > 125,000 / 1.85
x > 67,567.5......so to make a profit, they would have to sell at least 67,568 devices to make a profit <==
