Rational Because it can be simply as 3/1
In the problem given:
W + 15x - 9y + 2z
The term are single mathematical expressions that separate values.
In the expression, there is a + and -; these concludes 2 terms.
There are 3 coefficients next to each variable.
The coefficients are 15x, -9y, and 2z.
That means there are 3 coefficients.

(180 miles=7.5 hours, 20 miles=2.5/3=0.8333) 7.5+0.8333=8.3333 or 8h and 20 minutes.
To help you out I save your picture and explain the process. The only thing tht confuses me is problem #!6. But I hope I helped you out in the slightest bit
Answer:
Length of the bold arc = 72.63 ft
Step-by-step explanation:
Length of the arc = 
Here, θ = angle subtended by the arc at the center
r = Radius of the circle
Since, angle subtended by the bold arc at the center = 360 - 73
= 287°
And radius of the circle 'r' = 14.5 ft
By substituting these values in the formula,
Length of the bold arc = 
= 72.632
≈ 72.63 ft
Therefore, length of the bold arc = 72.63 ft
