Substitute the value of x = 2 to the equation:
R would equal -189, there is step by step in the picture
It’s 18x because 36 and 54 are both divisible by 18, and 18 can be divisible by 18 (making 1), resulting in 18 being the most common number between the numbers, whereas the ‘x’ is common between all 3 numbers and since the least amount of x is 1, the answer is just x without an exponent
(3 yard/sec) x (3,600 sec/hr) x (1 mile / 1,760 yard) =
(3 x 3,600 / 1,760) (mile/hour) = 6.136... mph (rounded)
