Answer:

A. t=13 B. K= 23 C. t= 1 3/8

Step-by-step explanation:

A. 2t-30m=20

30 x 1/5= 6

2t-6+6=20+6

2t/2=26/2

t=13

B. 14+m=2k

14+12=2k

14+12=46

46/2=23

k=23

C. 1/8r+t=1

1/8 x (-3)= -3/8

1 - (-3/8)= 1 3/8

t= 1 3/8

Hope it helps!

Answer:

18 3/4

Step-by-step explanation: You would simply subtract 26 5/8 - 7 7/8. You would have to make 26 5/8 into an improper fraction 25 13/8 and subtract that by 7 7/8 to equal 18 6/8 which you would then simplify into 18 3/4.
