Leni [432]

Answer:

Step-by-step explanation:

let : x the length and y the width    .... ( x  > y and x ; y reals numbers )

the perimeter is : 2(x+y)

2(x+y) = 55...(1)

x/y = 7/4 ...(2)

by (2) : x = (7/4)y

subsct in (1) : 2( (7/4)y +y ) =55

(7/2)y +2y =55

multiply by 2

7y +4y = 110

11y = 110

y = 10

x = (7/4)(10)

x = 35/2

zhenek [66]
Hi there,

5x?=110 ?=22

how? 110/5=22

now 2x?=110

110/2=55    ?=55'

so we know now that people bought 22 packages with card and 55 w/th out cards!

so no we need to divide 695/both

695/5=139 packages with cards 

695/2=347 packages without cards 

SO

139 packages with card 

347 packages without card
