3/1( 1/10)= 3/10
You put whole number over 1 then multiply it out.
The ten thousandth number in 14,620 is 1
the number to the right of 1 is 4
4>5
The answer is 10,000
Let x = one of the legs.
Then, the other leg = x + 3.
Ed will use the Pythagorean Theorem to find the hypotenuse.
So, let a = x one leg. Let b= x + 3 the other leg. And, let c = 15 the hypotenuse.
The Pythagorean Theorem is:
c^2 = a^2 + b^2, where a and b are the legs and c is the hypotenuse.
We have:
15^2 = x^2 + (x + 3)^2
225 = x^2 + x^2 + 6x + 9
Rearranging:
2x^2 + 6x - 216 = 0
Divide by 2:
x^2 + 3x - 108 = 0
Solve by factoring:
(x - 9)(x + 12) = 0
So, x = 9 and x = -12. (x = -12 is not a valid answer.)
x = 9
x + 3 = 12
Conclusion: The legs of the right triangle are 9 inches and 12 inches.

i dont really know how to make a line plot/dot plot on here but, 20; 1 x 21; no x's 22; 3 x's 23; 5 x's 24; 12 x's and 25 15 x's. (or whatever you use, you dont need to use x's, remember to keep them the same size.)
