solve 39 divided by 11 a. 3 5/11 b. 3 6/11 c. 11 1/2 d. 6 3/11 pls HURRY I HAVE NO IDEA WHAT IT IS!!!

 3 & 6/11 (choice B)

Work Shown:

39/11 = (33 + 6)/11

39/11 = (33/11) + (6/11)

39/11 = 3 + (6/11)

39/11 = 3 & 6/11

Or you could use a calculator to see that

39/11 = 3.545 approximately

The whole part is 3 which is the stuff to the left of the decimal point.

The remainder is 39-3*11 = 39-33 = 6 which is the numerator of the fractional part. Therefore the improper fraction 39/11 converts to the mixed number 3 & 6/11.

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.

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
