The product of 5 and a number, decreased by 9, is 310. what is the number?

Answer 1

5x-9=310 add 9 to each side
5x=319 divide by 5
x=63.8

Answer 2

5 X (x-9) = 310

Divide both sides by 5.

x - 9 = 310/5

x - 9 = 62

Add 9 to both sides.

x = 62 + 9

x = 71

Check your work.

5 X (71 - 9) = 310

5 X 62 = 310

P.S. I'm reading this problem as "The product of 5 and a number, [to be] decreased by 9, is 310."

Answer 3

*Break each part down separately into numerical data:

1. the product of 5 and a number means is 5x because, the product of two variables means multiplication and some unknown variable is represented as "x" til we solve it.

2. the product of 5 and a number (5x) is decreased by 9 means 9-5x because, decreased means subtraction and 5x is being subtracted from 9.

3. is 310 means equals to 310

*Rewrite the numerical data together:

9 - 5x = 310

First: subtract 9 from both sides:

9 - 9 - 5x = 310
-5x = -310

Second: solve for "x" by keeping it on one side by itself: divide both sides by -5:

-5x/-5 = -310/-5
x = 62

Answer 4

This number is:
5n-9=310
trans. -9 to the other side
5n=310+9 and n=319/5 or
n =63.8

Answer 5

The product is decreased by 9, so the equation reads:

5x-9 = 310

add 9 to each side

5x = 319

divide each side by 5

x = 319/5 or 63.8

The questions asks you to solve for the number (represented by x)... your solution is 63.8

Answer 6

TG is correct. the answer is 71. This can be easily verified:

71 - 9 = 62

5 x 62 = 310

Answer 7

(X * 5) - 9 = 310
(X * 5) - 9 + 9 = 310 + 9
(X * 5) = 319
(X * 5)/5 = 319 / 5
X = 319 / 5 = 63.8

Answer 8

let the number is : x
then
5x-9=310
5x=310+9
5x=319==> x=319/5

Answer 9

The equation that describes your question is:

5x-9=310

Hence
5x=319
x=319/5

Answer 10

71
