Answer: The answer is 500,000.

Step-by-step explanation:

100% - 30%  = 70%

          x   =>    100%

350000   =>      70%

x = 350000*100% / 70%

x = 500000

-2+y=9 3x-7y=3 solve the system by the substitution
kherson [118]

Hello from MrBillDoesMath!

Answer:

x = 80/3 ( 26 2/3)

y = 11


Discussion:

Step 1:

-2 + y = 9  =>                         add 2 to both sides

2 +  -2 + y = 9  +2 =>

y = 11

Step 2:

Substitute y = 11 (from Step 1) into

3x - 7y = 3  =>

3x - 7(11) = 3 =>               y = 11 from Step 1

3x - 77 = 3 =>                   add 77 to both sides

3x - 77 + 77 = 3 + 77 =>

3x = 80 =>

x = 80/3


Thank you,

MrB

Answer:

\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)}

Step-by-step explanation:

Quadratic formula: \frac{-b+-\sqrt{b^2-4ac} }{2a}

2x^2-1=3x+4\\\\2x^2-3x-5=0\\\\\\frac{-(-3)+-\sqrt{(-3)^2-4(2)(-5)}}{2(2)} \\\frac{3+-\sqrt{9+40} }{4}

x = \frac{3+-7}{4}

Hope this helps and God bless!
