Which of the following expressions is equivalent to 7 5/6+ 3/4

a- 7 7/10+3/5

b-7 7/8+6/16

c- 6 4/6+1 11/12

d- 7 3/4+2/3

   c

Step-by-step explanation: I added each one to see if it was equivalent the answer to the problem is 7 8/12 i got that by

7 + 5/6 + 4/3 finding the least common denominators

5/6 = 10/12

3/4 = 9/12 so the LCD is 12

10/12 + 9/12 = 19/12

19 divided by 12 equals 1 with a remainder of 7

19/12 = 1 7/12

7 + 1 + 7/12 = 8 7/12

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
