Answer: The correct option is A.
Explanation:
The given equation is,
Multiply both sides by 2.
![2[4(x+5)-5]=\frac{8x+18}{2}](https://tex.z-dn.net/?f=2%5B4%28x%2B5%29-5%5D%3D%5Cfrac%7B8x%2B18%7D%7B2%7D)
Subtract both sides by 8x.
This statement is false for any value of x, therefore the system of equation have no solution and option A is correct.
Answer:
300 doors.
Step-by-step explanation:

7.5 hours = 450 minutes.
Answer:
The total amount of recyclables sorted by Amirah is 931 pounds.
Step-by-step explanation:
Amount of cans and bottles sorted = 263 pounds
Amount of paper sorted = 668 pounds
So, the total amount of recyclables sorted
= amount of cans and bottle sorted + amount of paper sorted
= 263 pounds + 668 pounds
= 931 pounds
Hence, the total amount of recyclables sorted is 931 pounds.
Answer:
it would be <u>800</u> because 2.8% of <u>800</u> is 22.40 and that is your answer.
hope i helped :)
Recall the double angle identity,
sin(2x) = 2 sin(x) cos(x)
Then we can write
sin(9x) cos(9x) = 1/2 sin(2 • 9x) = 1/2 sin(18x)
Then
∫ sin(9x) cos(9x) dx
= 1/2 ∫ sin(18x) dx
= -1/2 • 1/18 cos(18x) + C
= -1/36 cos(18x) + C
though you could continue with another double angle identity,
cos(2x) = cos²(x) - sin²(x)
to rewrite the antiderivative as
= -1/36 (cos²(9x) - sin²(9x)) + C
= 1/36 (sin²(9x) - cos²(9x)) + C
