Use any method to solve the equation. If necessary, round to the nearest hundredth.7x2 − 16x = 8

Semmy [17]

7x^2 - 16x - 8 = 0

using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7

= (16 +/1 sqrt 480) / 14

= 2.71, -0.42 to nearest hundredth

The amount and the concentration of a salt solution is given. How much salt would you get if you evaporated all water from this

DiKsa [7]

Answer:

40.5 g

Step-by-step explanation:

Find how much salt is in 450 g of a 9% salt solution.

Note that

450 g - 100%,

x g - 9%,

then

$\dfrac{450}{x}=\dfrac{100}{9},\\ \\x=\dfrac{450\cdot 9}{100}=40.5\ g.$

If you evaporated all water from this solution, then you would get 40.5 g of salt.
