Answer:
y=2/3x -7
Step-by-step explanation:
4x -6y=42
-4x = -4x +42
-6y= -4x + 42
-6 -6 -6 divide both sides by -6
y= 4/6x -7 simplify
y= 2/3x -7
Answer k=16
A recipe says to use 3 cups of flour to make 48 cookies.
the number of cookies made, y, to the number of cups of flour used,x .
Than
y = kx
Where k is the constant of proportionality.
48 = 3k
k = 16
Therefore the constant of proportionality is 16.
Answer: x(2+2x-15)

<h2>
Answer:</h2>
$52.63
<h2>
Step-by-step explanation:</h2>
To find 20% of $43.86 we multiply $43.86 by 0.2
$43.86 • 0.2 = $8.772
Now add $43.86 and $8.772 to find out how much the family paid altogether.
$43.86 + $8.772 = $52.632
In money the smallest place value is cents so we have to round to the hundredths place.
Doing this we get the grand answer of:
$52.63
