Let Brian's steps have a measure of 1, and Richard's steps have a measure of k. Then after each walks 5 steps away from the other, their distance apart is
... 5 + 5k
We are told that distance is equal to 9 of Richard's steps, so is equal to 9k.
... 5 + 5k = 9k
... 5 = 4k . . . . . . . subtract 5k
... 5/4 = k . . . . . . divide by 4
Richard's steps are 5/4 the size of Brian's steps. The appropriate selection is
... b) 5/4
First, let's simplify the inequality as much as we can:
-4x + 7 > 15
-4x > 8
Divide by -4:
x < -2
Answer:
5 x - 2x + 7 - x = 2x + 7
Step-by-step explanation:
simplify
(5x - 2x - x) = 2x
2x + 7 = 2x + 7
Since the side of the square frame is 15x, the area of the frame in whole would be:
(15x)² = 225x²
Now if we subtract out the circle mirror with a radius of 5x, we get:
225x² - πr²
225x² - π(5x)²
225x² - π25x²
We can factor out a 25x² and get:
25x² (9 - π)
