julsineya [31]

let

x--------> the monthly fee

y--------> the administration fee

we know that

$660=y+12x$ --------> equation $1$

$810=y+15x$ --------> equation $2$

Multiply by $-1$ equation $1$

$-660=-y-12x$ ------> equation $3$

Adds equation $2$ and equation $3$

$810=y+15x\\-660=-y-12x\\---------\\ 810-660=15x-12x\\ 3x=150\\ x=50\ dollars$

Find the value of y

$660=y+12x\\ 660=y+12*50\\ y=660-600\\ y=60\ dollars$

therefore

the answer is

the administration fee is equal to $60\ dollars$

Solve each problem by writing an inequality. The length of a rectangular yard is 30 meters. The perimeter is at most 90 meters.

klio [65]

15 is the width because 30 times 2 equals 60 and 60 plus 30 equals 90 so 30/2 equals fifteen.

In short-30*2+w2=90

w=15
