Today, Abigail has brought 12 sandwiches to share with friends at
horsena [70]

Answer:

58%

Step-by-step explanation:

The first thing that you have to do if figure out how many sandwiches are left we do this by the total - bad sandwiches = good sandwiches

12-5=7

There are 7 good sandwiches left. To figure out the percentage you do       \frac{part}{total}=\frac{percent}{100}     now we fill in the parts the part is 7, the total is 12 and the % is x

\frac{7}{12}=\frac{x}{100}          now we cross multiply, 7 x 100 and 12 x X

700=12x          now we divide both sides by 12 so the x is alone

x = 58.33            now we round down because it ends in.3

x=58

Solve x2 = 12x – 15 by completing the square. Which is the solution set of the equation?
REY [17]
X ·2 = 12x - 15

2x = 12x - 15

2x + (-12x) = (12x - 15) + (-12x)

A zoo keeper wants to fence a rectangular habitat for goats. The length of the habitat should be at least 80 feet, and the perim
Bogdan [553]

Let x ft be the lenght of the fence and y ft be the width of the fence.

1. The length of the habitat should be at least 80 feet, then

x\ge 80\ ft.

2. The perimeter of the habitat should be no more than 300 feet. The perimeter of the fenceis 2x+2y ft, then

2x+2y\le 300\ ft.

3. The system of inequalities that represent the model is

\left\{\begin{array}{l}x\ge 80\\2x+2y\le 300\end{array}\right..

The graph of these inequalities is attached.

Two possible solutions are

  1. x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);
  2. x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).
