Combine -3 and 2 so id be -x and combine -5 and 10 so id be 5y so the answer would be -x + 5y

They are basically like groups. Take -3x+2x , Just do -3 +2 = -1 and then just add the x. So -1x. Next you have -5y+10y . Just do -5 + 10 = 5 and remember to add the x on so your final answer should be -1x + 5y

Answer:

3. d= 20mm

4. r= 8 in

5. d= 14 mi

6. r= 11 yd

Step-by-step explanation:

Radius is half of diameter.

Example:

What is the diameter of a circle with a radius of 4?

If r = 4, d = 8

Do radius times 2.

Example 2:

What is the radius of a circle with a diameter of 10?

D = 10, so r = 5

Do diameter divided by 2.
