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
9514 1404 393
Answer:
x = -(9/7)n -81
Step-by-step explanation:
Subtract the n term.
x/-9 = 9 -n/-7
Multiply by -9.
x = -81 -(9/7)n
Answer y=-4
Because it's like you do if backwards
