The width of a rectangle is five more than triple the length. The perimeter of the rectangle is 66 centimeters. What are the dimensions of the rectangle?

L=7cm

W= 26cm

Step-by-step explanation:

Step one

Given data

let the lenght be x

L= x

W= 3x+5

P= 66

Step two:

P=2L+2W

substitute

66= 2x+2(3x+5)

66= 2x+6x+10

66= 8x+10

collect like terms

66-10= 8x

56= 8x

x= 7cm

L= 7cm

W= 3(7)+5

W= 21+5

W= 26cm

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
