Answer:
It takes 6 hours for both to reach an equal paid.
Step-by-step explanation:
You have to form an expressions in terms of x where x determine the number of hours :
Option 1,
$(30 + 9x)
Option 2,
$(14x)
Next, you have to compare it since they want to find out how many hours they work until they reach the same amount :
30 + 9x = 14x
30 = 14x - 9x
30 = 5x
5x = 30
x = 30÷5
x = 6
So you express fraction.
15 x (1/3)^ 3=15/27=5/9
Answer:
35 i think is the answer but im probably wrong
Step-by-step explanation:

47 decreased by 9d = 47 - 9d
= 47 - 9d.
A) 68.8
b) 5.9
