For the following questions, solve for the missing rate, base or product (round to the nearest hundredth if needed): 25% of 320 is

80

Step-by-step explanation:

let the unknown value be x.

Step-by-step explanation:

% means out of hundred and of means to multiply.

=>

=> 0.25 * 320

=> 80

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)

hi! i think the answer is 1/2 : )
