What is the width (w) of the pound, in feet?

12

Step-by-step explanation:

1. Use the Pythagorean Theorem to solve: a^2+b^2=c^2.

Here you are given the hypotenuse (which is always c in the formula), and one other leg that could be either a or b.

2. Plug these numbers into the formula and evaluate them.

a^2 + 16^2 = 20^2

16 x 16 =256

20 x 20 = 400

So that gives you a^2 + 256 = 400.

3. Subtract 256 from both sides and take the square root of the result.

400 - 256 = 144

a^2 = 144

= 12

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
