Well, Lets Look At Their Factors.
21: 1, 3, 7, 21
30: 1, 2, 3, 5, 6, 10, 15, 30
Since One Does Not Count For Least Common Factors, We go To The Next One They Both Have, 3!!
So, The Answer Is 3.

The equation of a line is 2/5x+1/10y=2<br> The x-intercept of the line is and it’s y-intercept is
Oksi-84 [34.3K]

For this case we have the following equation of a line:

\frac {2} {5} x + \frac {1} {10} y = 2

To find the point of intersection with the x axis, we make y = 0:

\frac {2} {5} x + \frac {1} {10} (0) = 2\\\frac {2} {5} x = 2

We clear the value of "x":

x = \frac {2 * 5} {2}\\x = 5

So, the x-intercept of the line is 5.

To find the point of intersection with the y axis, we make x = 0:

\frac {2} {5} (0) + \frac {1} {10} y = 2\\\frac {1} {10} y = 2

We clear the value of "and":

y = \frac {10 * 2} {1}\\y = 20

So, the y-intercept of the line is 20.

Answer:

x = 5\\y = 20
