What is 12 inches in length

Here is ur answer

30.48 centimeters

Step-by-step explanation:

Here your "What is 12 inches in length?" question answers itself.  Not trying to be funny, but "12 inches in length" is just that:  a length of 12 inches.

If you want this result in a different unit of measurement, go ahead and use the correct conversion factor or factor.

12 inches is 1 foot, both measures of length

Since 1 meter = 39.37 foot,

                   1 meter

12 inches = 0.305 meter

                   39.37 in

and so on.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
