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.

Math solve for x pls
olchik [2.2K]

Answer:

26

Step-by-step explanation:

Plug in 15 for y in the first problem so instead of y=x-11 it would be 15=x-11

15=x-11

+11= +11 (you want to add 11 to both sides to get x by its self)

26=x

!!!!!!! Why isn't A the correct answer? I am having trouble to reason why A is wrong so please help if can!
docker41 [41]

Answer:

d.  x = -3

Step-by-step explanation:

<u />\sqrt{(x + 3)}÷ (x+8)(x-2) = 0

f(x) / g(x) = 0

Variable x cannot be equal to any of the values −8,2 since division by zero is not defined. Multiply both sides of the equation by (x−2)(x+8).

<u />\sqrt{(x + 3)} = 0 ------ square both sides

x + 3 = 0

solve for x:

x = -3
