What is 6 1/3−1 2/3?

Answers

Answer:

4 2/3!

Step-by-step explanation:

Answer: [tex]4 \frac{2}{3}[/tex]

Step-by-step explanation:

Lets start by subtracting 6 by 1.

       

                  6 - 1 = 5

Now we need to subtract 1/3 by 2/3. Which means we will need to take one from the 5 and add it to the 1/3. So we get [tex]1 \frac{1}{3}[/tex]. Now we subtract 1 1/3 by 2/3. The answer to that is 2/3.

So our answer is 4 2/3

6= x=20 ur welcome

Answer: x = 8, x = 5

Step-by-step explanation:

first problem: first, we collect like terms

3x + 3 = 2x + 11

then, we move the terms around.

3x - 2x = 11 - 3

finally, we collect those like terms and calculate.

x = 8

second problem: first, we rewrite the expression

2 x 3x + 1 = 2x + 21

then, we calculate.

6x + 1 = 2x + 21

next, we move the terms,

6x - 2x = 21 - 1

then, we collect the like terms.

4x = 20

finally, we divide both sides.

x = 5

If a circle has a diameter of 23 inches, then the radius will be

Answers

Answer:

11.5 in

Step-by-step explanation:

The radius is half the diameter

23/2=11.5

If a circle has a diameter of 23 inches, then the radius will be 12.5 inches.

What is the relation between the radius and the diameter of the circle?

The radius is half of the diameter of the circle, for calculating radius we can divide the diameter of the circle by 2.

Given that,

The diameter of the circle is equal to 23 inches.

d = 23 inches

It is known that,

The radius is half of the diameter of the circle,

so it can be written in the form expression as:

r  = D/2

D = 23 inches

r  = 23/2

  =  12.5 inches

Hence, the radius of the circle 12.5 inches.
