Answer: 6 x (x+5)
Step-by-step explanation: Since it is six times a number AND five, you want to do the addition equation first. To show this you place parentheses around a variable (x) plus 5. You add six in front of this because it comes first in the word problem.
Answer:
6(x+5)
Step-by-step explanation:

k/x = xy/x
y = k/x
2.Substitute

y = 0.777......
y = 0.8 (Answer)
To confirm
k = 9 × 0.8
k = 7.2
k = 7 (constant)
