The length of a rectangle is 5.9 cm more than 3 times the width. If the perimeter of the rectangle is 57.4cm, what are it's dime

navik [9.2K]

Answer:

l = 23 cm and w = 5.7 cm

Step-by-step explanation:

Perimeter = twice the length plus twice the width

let w = width

let l = length

l = 5.9 + 3w

57.4 = 2(5.9 + 3w) + 2w

57.4 = 11.8 + 6w + 2w

57.4 = 11.8 + 8w

45.6 = 8w

w = 5.7

Substitute 5.7 for 'w' to get 'l':

l = 5.9 + 3(5.7)

l = 23

The sum of the ages of Mr Lee and his son is 53 now. 4 years ago, the age of Mr Lee was 4 times that of his son. Find their ages

zepelin [54]

Answer:

Now, Mr Lee's age is 40 years, his son's age is 13 years.

Step-by-step explanation:

<u>4 years ago:</u>

Son's age = x years

Mr. Lee age = 4x years

Son's age = x + 4 years

Mr. Lee age = 4x + 4 years

The sum of the ages of Mr Lee and his son is 53 now, so

$x+4+4x+4=53\\ \\x+4x=53-4-4\\ \\5x=53-8\\ \\5x=45\\ \\x=9\\ \\4x=36\\ \\x+4=9+4=13\\ \\4x+4=36+4=40$

Now, Mr Lee's age is 40 years, his son's age is 13 years.
