Gail took part in a quiz show and won half a million pounds she spends 120000 pounds on a sports car. Then spends half of the money left on a apartment. How much was gails apartment?

190,000 pounds

Step-by-step explanation:

Amount won by Gail= 500,000

Amount spent on sports car= 120,000

Money left = Amount won minus amount spent on sports car

= 500,000 - 120,000

= 380,000

Then she spends half of the amount left on her apartment

= 1/2 of 380,000

= 1/2 × 380,000

= 190,000

Her apartment costs 190,000 pounds

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!

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)
