SSSSS [86.1K]3 years ago
4 0

Answer:

The number is 4

Step-by-step explanation:

Let the number be  n

Twice the number : 2*n = 2n

Half the number : 1/2 n

2n+ \frac{n}{2}=10\\\\\frac{2n*2}{2}+\frac{n}{2}=10\\\\\frac{4n}{2}+\frac{n}{2}=10\\\\\frac{5n}{2}=10\\\\5n=10*2\\\\5n=20\\\\n=\frac{20}{5}\\\\

n = 4

First you need to substitute the xs and ys into point slope ( y1 - y2 = m(x1 - x2). in this example it would be 3-6= m(0 - (-1)). then you just simplify, so -3 = m(1) -3=m. the slop is -3. because you already know the y-intercept is 3 (0,3), you can substitute everything into slope intercept (y=mx+b). so the answer is y=-3x+3.

I hope this helped, let me know if you are still confused and i can help :)

vagabundo [1.1K]
First, we determine the area of the piece of cardboard by multiplying its dimensions. 
                area of cardboard = (8.5 inches) x (11 inches) = 93.5 in²
Then, we solve for the area of the cut out square,
              area of the square = (4 inches) x (4 inches) = 16 in²
Then, we subtract the areas giving us the area of the frame which is equal to,
                          77.5 in²
