Sadie brought $28.00 to the art supply store. She bought a brush, a sketchbook, and a paint set. The brush was 1/3 as much as th
Digiron [165]

Answer:

cost of paint set = $ 13.64

cost of sketch book = $ 6.82

cost of brush = $ 4.55

Step-by-step explanation:

Let the cost of paint set is s.

cost of sketch book = s/2

cost of brush = s/3

Money spent = $ 28 - $ 3 = $ 25

So,

s +  s/2 + s/3 = 25

6 s + 3 s + 2 s = 150

11 s = 150

s = $ 13.64

cost of paint set = $ 13.64

cost of sketch book = $ 6.82

cost of brush = $ 4.55

Answer:

<h2>A)x=3/2 y=½</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • system of linear equation
  • PEMDAS
<h3>let's solve:</h3>
  • since y is equal to both equation therefore we can substitute the value of y into the other equation
  1. \sf substitute \: the \: value \: of \: y :  \\  \sf  - x + 2 = 3x - 4
  2. \sf add \: x \: to \: both \: sides :  \\  \sf  - x + x + 2 = 3x + x - 4 \\  \sf 4x - 4 = 2
  3. \sf add \: 4 \: to \: both \: sides :  \\  \sf xx - 4 + 4 = 2 + 4 \\ 4x = 6
  4. \sf divide \: both \: sides \: by \: 4 :  \\  \frac{4x}{4}  =  \frac{6}{4}  \\ x =  \frac{3}{2}

let's figure out y

  1. substitute the got value of x into the second equation: y=3*3/2 -4
  2. simplify multiplication:9/2 -4
  3. simplify division:4.5-4
  4. substract:0.5 alternate form:y=½
