20/28 = 3x / (4x + 2)

84x = 20(4x + 2)
84x - 80x =  40
4x = 40 
x = 10

so the 2  lines are equal to  30 and  42

Jabary is thinking of 3 numbers the greatest number is twice as large as the least number the middle number is 3 more than the l
antiseptic1488 [7]
A + b +c = 75; where a is the greatest number; b is the middle number; c is the least number;

a = 2 * c;

b = 3 + c;

then, 2 * c + 3 + c + c = 75 => 4 * c = 72 => c = 72 / 4 => c = 18 => a = 2 * 18 => a = 36; b = 3 + 18 => b = 21;

Find the slope of the line y=-1/4x+9
Basile [38]

Answer:

slope = - \frac{1}{4}

Step-by-step explanation:

The equation of a line in slope0 intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - \frac{1}{4} x + 9 ← is in slope- intercept form

with slope m = - \frac{1}{4}

Chris wants to fence three sides of a rectangular exercise yard for his dog. The fourth side of the exercise yard will be a side
Semmy [17]

Answer:

  • parallel: 60 ft
  • perpendicular: 30 ft
  • area: 1800 ft^2

Step-by-step explanation:

Let x represent the length of fence parallel to the house. Then the length perpendicular is ...

  y = (120 -x)/2

The area of the yard is the product of these dimensions, so is ...

  A = xy = x(120-x)/2

This is the equation of a parabola that opens downward and has zeros at x=0 and x=120. The maximum (vertex) is on the line of symmetry, halfway between these zeros, at x=60.

The fence parallel to the house is 60 feet.

The fence perpendicular to the house is (120-60)/2 = 30 feet.

The area of the yard is (60 ft)(30 ft) = 1800 ft^2.
