A. 352 seconds or 5 minutes 52 seconds.
B. 320 seconds or 5 minutes and 20 seconds
C. 27687 steps
There are 5280 feet per mile. In A, 3 strides per second at 5 feet gives us 15 ft per second. 5280/15 = 352 seconds. In B, 3 strides per second at 5.5 feet gives us 16.5 feet per second. 5280/16.5 = 320 seconds. In C, we calculate the total feet to divide by 5 per step. multiply 26 miles by 5280 to get feet per mile and multiply 385 by 3 to get the feet per yard. Add them together. then divide by 5. 26(5280) + 385(3) =138435. 138435/5 = 27687 steps
The answer is 49.89

Answer:
One.
Step-by-step explanation:
-4x + 6 = 6x - 2
-4x - 6x = -2 - 6
-10x = -8
There's only value of x which, when multiplied by -10 would produce -8.
That value is 0.8.
-10 * 0.8 = -8
No other value can produce the same result.
This means that there's only one solution.
