Then figure for the professional costs. Put it in perspective of a year. 45*11+75=570.
Then subtract. Professional- DIY. 570-479=91.
$91 is about 2 months worth of work. So a year has 12 months.
12-2=10
Answer:10 months
Professional Service Option Do-It-Yourself Option:
First month lawnmower = $250
Initial visit = $135
Price for mowing and edging = $69
Price for lawn and bushes trimming = $ 25
Hence, total cost becomes = 250+135+69+25 = $479
Professional service cost for 1 month lawnmower = $75
Professional cost for visit for 11 months (1st visit costs $135) = $45
Total cost for 11 months = 45*11 = $495
Total professional cost = 495+75 = $570
Now, subtracting the professional cost and do it yourself cost we get;
$570-$479=$91.
This $91 is for 2 months worth of work. Hence, months needed to recover costs = 12-2 = 10 months
Hence, the answer is 10 months.

Answers
The radius r is half the diameter. The diameter is 10 ft so the radius is 5 ft.
The area is 25π ft².
A = pi * r^2
If the diameter is 10 feet, the radius will be half of that or 5.
So:
A = 3.14 * 5^2
Simplify exponent:
A = 3.14 * 25
Multiply:
A = 78.5

Answer:
Easy
Step-by-step explanation:
-19-9=-28
-28/-4=7
thus x=7
Final answer:
In solving the equation 9 - 4x = -19, we find that x = 7 is indeed the correct solution.
Explanation:
The given equation is 9 - 4x = -19. We are to solve this equation for x, and see if it equals 7, as stated in the question. Start by subtracting 9 from both sides, resulting in: -4x = -28. Next, divide both sides by -4 to solve for x, resulting in x = 7. So, indeed, for the given equation, x = 7 is the correct solution.
