Sally's investment of £450 has gone up by 30 percent, while susie's investment of £650 has gone done by 10 percent. Who now has the larger amount of money

Neither, they have the same amount now?

Step-by-step explanation:

Sally = £450 = 100%

Gone up by 30% so 100% + 30% = 130% = 1.3

£450 x 1.3 = £585

Susie = £650 = 100%

Gone down by 10% so 100% - 10% = 90% = 0.9

£650 x 0.9 = £585

step-by-step explanation:

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)
