what is -3/4 – (-1/2)?
a. -5/4
b. -1/4
c. 1/4
d. 1/2

-1/4

Step-by-step explanation:

-3/4 - (-1/2)

-- = +

-(-1/2) = + 1/2

-3/4 + 1/2

The denominator of 1/2 needs to be the same as -3/4. What makes 1/2 have the same denominator as -3/4? Divide 4 by 2.

4/2 = 2

So, we must multiply both the top and bottom of one half by 2.

1 * 2 = 2

2 * 2 = 4

2/4

-3/4 + 2/4

Just add the top.

-3 + 2 = -1

-1/4

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
