A number is divided by 3. Then 14 is added to the quotient. The result is 33. What is the orginal number?
seropon [69]

let "a number" = x

a number is divided by 3 => x/3

14 is added to the quotient => (x/3) + 14

The result is 33 => " = 33"

Solve for x

(x/3) + 14 = 33

Isolate the x. Note the equal sign. What you do to one side you do the other.

Subtract 14 from both sides

(x/3) + 14 (-14) = 33 (-14)

x/3 = 19

Isolate the x. Multiply 3 to both sides

x/3(3) = 19(3)

x = 19(3)

x = 57

57 is your original number

hope this helps

The circle below has a radius of 3 units . Find the area of the circle. Use 3.14 for π.
const2013 [10]

Answer:

28.26 units

Step-by-step explanation:

We know the radius of the circle is 3 units, so we'll end up plugging that into the formula.

A = π(3^2) or A = π * 3 * 3

When you substitute pi for 3.14, you'll end up getting 28.26 units.

Hope this helped! :)

10[4 times 10 divided by (6^2-4^2) +1]
Genrish500 [490]

Answer:

19

Step-by-step explanation:

10[4 times 10 divided by (6^2-4^2) +1]

First you would multiply 6 x 6 = 36

10[4 times 10 divided by (36-4^2) +1]

Second you would multiply 4 x 4 = 16

10[4 times 10 divided by (36-16) +1]

Third you would subtract 36 - 16 = 20

10[4 times 10 divided by 20 +1]

Fourth you would add 20 + 1 = 21

10[4 times 10 divided by 21]

Fifth you would multiply 4 x 10 = 40

10[40 divided by 21]

Sixth you would divide 40 divided by 21 = 1.90

10[1.90]

Seventh you would multiply 10 x 1.90 = 19

Your answer would be 19.

Hope this helps. I am sorry if you get this wrong.
