Use 3.14 for .jenna is planting four circular gardens. she is planting one garden each for tomatoes, carrots, cabbage, and strawberries. each garden will have a fence around it to keep rabbits out. the tomato, carrot, and cabbage gardens will all be the same size. since jenna loves strawberries, the strawberry garden will be larger. it will use the same amount of fencing as the other three gardens combined. she used a total of about 113.04 feet of fencing material.

Um I assume you're wanting the circumferences of the fences so we have 3 that are all the same size and one that is 3 times as large as any of the others

so here's our equations

3x+y=113.04

y=3x

use substitution

3x+3x=113.04

6x= 113.04

now the question says use 3.14 so I'm thinking you want the answer in terms of pi so first divide 113.04 by 3.14

6x=36pi

x=6pi now substitute that back in for x in one of your equations

y=(3)(6pi)

y=18pi

so the tomatoes carrots and cabbage will all have a circumference of 6pi and the strawberries 18pi

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
