The length of a rectangle is 8 inches more than three times the width. the perimeter is 88 inches. find the length and width.
Sav [38]
We can say L as length and W as the width 

L= 3w + 8 

The formula for perimeter is 2L + 2W = P. We can substitute L in as "3w+8" to make the equation... 

2(3w+8)+2w=88        Now, we can simplify by distributing the 2 to each term
6w+16+2w=88
8w+16=88               Then subtract 16 from each side..
8w=72
w=9

So the width is 9, so we can substitue that into the previous equation, L = 3w+8. 

L=3(9)+8
L=27+8
L=35, W=9

Rainbow [258]

The exhibition of 7 birds will cost $2,450

<h3>How to calculate the total cost ?</h3>

The wildlife center charges a basic fee of $325 for a bird exhibition

When 5 birds were exhibited, $125 additional fee was charged

The additional fee for a bird is

= 125/5

= 25

Therefore the total cost of exhibiting 7 birds can be calculated as follows

= 325 + 25

= 350

350 × 7

= 2,450

Hence the total cost for the exhibition of 7 birds is $2,450

2x - 3y = -4 if x + 3y = 7
Anvisha [2.4K]
(2x-3y=-4)-2(x+3y=7)

2x-3y-2x-6y=-4-14

-9y=-18

y=2, making x+3y=7 become:

x+6=7

x=1

So the solution to the system of equations is the point (1,2)
