5(x+y)= 20+ 3x
5x+5y=20+3x
5x+5y-3x=20+3x-3x
2x+5y=20
2x+5y-2x=20-2x
5y=-2x+20
5y/5=-2x/5+20/5
y=-2/5x+4

ANSWER: y=-2/5x+4

Answer:

???

Step-by-step explanation:

5x+5y=20+3x (distribution)

-3x -3x (alike terms)

2x+5y=20

/2x /2x

5y=20/2x

/5 /5

y=20 (idk I put it in my calculator)

if that looks nothing like the correct answer just put 0 for x and solve from there

5(0)= 0, so

5y=20 (because the three also has an x which we are putting as zero)

divide 20 by 5 and get 4

I'm really sorry if this is wrong it's been a long day

Answer:

<em>The true statements are:</em>

<em>*The median weight for shelter A is greater than shelter B.</em>

<em>*The (IQR) interquartile range of shelter A is greater than the (IQR) interquartile range of shelter B.</em>

Step-by-step explanation:

<em>(for shelter A)</em>

median: 21

lowest value: 8

highest value: 30

lower quartile: 17

upper quartile: 28

(IQR) interquartile range: 28 - 17 = 11

Range: 30 - 8 = 22

<em>(for shelter B)</em>

median: 18

lowest value: 10

highest value: 28

lower quartile: 16

upper quartile: 20

(IQR) interquartile range: 20 - 16 = 4

Range: 28 - 10 = 18

~phew!, this took me long xd, hope this helps you~

Answer:

Only choices C and D are solutions

Step-by-step explanation:

6x + 3y = -15

y = -2x - 5

6x + 3y = -15

6x + 3(-2x - 5) = -15

6x - 6x - 15 = -15

0 = 0

Since 0 = 0 is a true statement, both equations of this system are the same equation and represent a single line on the coordinate plane.

We need to check each choice in just one equation.

Let's use the second equation.

y = -2x - 5

A.

(2, 7)

7 = -2(2) - 5

7 = -4 - 5

7 = -9   False

Not a solution

B.

(5, 0)

0 = -2(5) - 5

0 = -10 - 5

0 = -15     False

Not a solution

C.

(-3, 1)

1 = -2(-3) - 5

1 = 6 - 5

1 = 1   True

Solution

D.

-13 = -2(4) - 5

-13 = -8 - 5

-13 = -13    True

Solution

Answer: Only choices C and D are solutions
