12/15 = 8/k k = ? Please helppp

10

Step-by-step explanation:

you can cross multiply.

after you cross multiply:

12k=120

k=10

d=-5

Step-by-step explanation:

5/8(16+24)=6(d-1)+1

distribute 5/8 into (16d+24) and 6 into (d-1)

10d+15=6d-6

subtract 6d on both sides

10d-6d+15=-6

combine like terms

4d+14=-6

subtract 14 on both sides

4d=-20

divide both sides by 4

d=-5

hope this helps
