Answer:

2 1/4

Step-by-step explanation:

- 5 1/4- [-7 1/2]

Get a common denominator of 4

- 5 1/4- [-7 1/2*2/2]

- 5 1/4- [-7 2/4]

We know subtracting a negative is adding

- 5 1/4 + [7 2/4]

Rewriting

7 2/4 - 5 1/4

Subtract the whole numbers

7-5 =2

Subtract the fractions

2/4 -1/4 = 1/4

2 1/4

Find the distance bewteen points H(8,4) and k(7,6) to the nearest hundreath
OleMash [197]

Answer:

2.24

Step-by-step explanation:

If you look at the points on the graph, you can see that the distance between them is also the hypotenuse of a right triangle, meaning you can calculate the distance using the pythagorean theorem.

a^2+b^2=c^2\\1^2+2^2=c^2\\1+4=c^2\\c=\sqrt{5}\\c\approx2.2361
