Answer: you spent 250 hours during your cleanup.
you spent 150 hours painting
Step-by-step explanation:
Let x represent the number of hours that you spent during your cleanup.
Let y represent the number of hours that you spent painting.
you earn $8 an hour cleaning up and $12 an hour painting last summer and you earned $3800 . it means that
8x + 12y = 3800- - - - - - - - - -- 1
You worked a total of 400 hours. This means that
x + y = 400
Substituting x = 400 - y into equation 1, it becomes
8(400 - y) + 12y = 3800
3200 - 8y + 12y = 3800
- 8y + 12y = 3800 - 3200
4y = 600
y = 600/4 = 150 hours
Substituting y = 150 into x = 400 - y, it becomes
x = 400 - 150
x = 250 hours
time = miles divided by speed
t = time
t = 975 miles / 65 mph
975/65 = 15 hours
Answer: so the answer is -9 + 23*7 = 152
Step-by-step explanation: a24 = a1 + (24-1)d where a1 = -9 and d = common difference ( 12-5 = 7)
Hope this helped :D
Why did you post this then?
For this you would want to break this figure up with familar shapes. You can do two triangles and one big rectangle.
First triangle:
(3)(2)(1/2)= 3 feet squared
Second Triangle:
(3)(4)(1/2)= 6 feet squared
Rectangle:
(11)(3)= 33 feet squared
Now you add:
33+3+6= 42 feet squared
So, for this hole you will need 42 feet squared of outdoor carpet
