Answer:
c/-9+6=14
c/-9=14-6
c/-9=8
c=8×(-9)
c= -72
Therefore the answer is (b)
Answer:

Step-by-step explanation:
Circumference = C = 31.4 ft
We know that,
<h3>C = 2πr</h3>
Where, r is the radius
31.4 = 2(3.14)r
31.4 = 6.28(r)
Divide 6.28 to both sides
31.4/6.28 = r
5 ft. = r
<h3>r = 5 ft.</h3>
Now,
<h3><u>Finding area:</u></h3>
A = πr²
A = (3.14)(5)²
A = (3.14)(25)
<h3>
A = 78.5 ft²</h3>

Answer: The answer is that he cleaned one room
Step-by-step explanation:
Because he charged in total 77 dollars and he charged 77 dollars per room, so 77*1=77=c
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
I think it might be 11x-8
I'm really sorry if that's wrong
