Answer:

x=8

y=18

Step-by-step explanation:

$(3x+13)+(7x-3)=90$

$10x+10=90$

$10x=90-10$

$x=\frac{80}{10} =8$

$3x+13=3(8)+13=24+13=37$

$5y=180-37-53=90$

$y=\frac{90}{5} =18$

I hope this help you

Amelia and Joey decided to shoot arrows at a simple target with a large outer ring and a smaller bull's-eye. Amelia went first a

Alona [7]

Answer:

outer ring worth 14 pts

bull's-eye worth 74.333333 pts

Step-by-step explanation:

let the worth point of landing an arrow on the outer ring be "x" and on bull's eye be "y"

For amelia

$3x + 3y = 267$

For joey

$4x + 3y = 281$

subtracting the first equation from the second

$x = 14$

$3x + 3y = 267$

$42 + 3y = 267$

$3y = 223$

$y = 74.333$

Please give the code word and the method as to how you did it

Answer:

1. true 2. true 3. false 4. false 5. false

15 + 15 + 10 + 10 + 10 = 60/5 = 12 ( CODE WORD)

Step-by-step explanation:

1. There are different forms of linear equations. Slope intercept has it's equation y = mx + b

2. A proportional relationship has a constant rate of change.

ex: y =2x +5, then the rate of change is 2 and it only ever rises by 2.

3. A proportional relationship must pass through the origin in order to be a proportional relationship.

4. The variable M in slope-intercept form represents the slope. B represents the Y-intercept.

5. Standard form for a linear equation is Ax+By=C. Y = MX+B is slope-intercept form.

CODE WORD: 12 or Twelve is correct because 12 is the mean of all 5 answers.
