Answer:

£30

Step-by-step explanation:

Let Brian initially had money in his wallet = £x

and Colin had the money = £y

Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1

Therefore,  

⇒ x = 5y -------(1)

Brian spent £27 that day, so money left with him = £(x - 27)

After spending the money Brian had £3 less than Colin.

(x - 27) = (y - 3)

x = y + 27 - 3

x = y + 24 -------(2)

Now we equate the equations (1) and (2) for the value of x,

5y = y + 24

5y - y = 24

4y = 24

y = £6

From equation (2),

x = 6 + 24

x = £30

Therefore, Brian initially had £30.

i hope this helps

My brainy brother and sister added their ages together and got 15. When they multiplied their ages together, they got 54. How ol
Vinvika [58]

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

x+y=15

x=15-y                ...(i)

Product of their ages = 54

xy=54

(15-y)y=54                [Using (i)]

15y-y^2=54

0=54-15y+y^2

Splitting the middle term, we get

54-15y+y^2=0

54-9y-6y+y^2=0

9(6-y)-y(6-y)=0

(6-y)(9-y)=0

Using zero product property, we get

(6-y)=0\text{ and }(9-y)=0

y=6\text{ and }y=9

If y=6, then using (i), we get

x=15-6

x=9

If y=9, then using (i), we get

x=15-9

x=6

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.

The perimeter of a rectangle is 2w+2l.
l=3w+9
2l=6w+18
2l+2w=8w+18
P=8w+18
66=8w+18
48=8w
W=6
