I believe all you do is add the numbers with the same coefficients so 2x + 5x + x (in front of x is understood to be a 1) So you get 8x. And 8 + 1 is 9 so the perimeter is B. 8x + 9

Suppose Lin labels the books at a constant speed of s books per minute. There can be several equations written that represent th
Alla [95]

Answer:

S = \frac{b}{m}

Step-by-step explanation:

Given

Speed = s

Required

Determine the expression for s

The speed is calculated as:

Speed = \frac{Number\ of\ books}{Time}

Substitute S for speed

S= \frac{Number\ of\ books}{Time}

Let the number of books be b and the time be m.

The expression becomes

S = \frac{b}{m}

Hence, the expression for the scenario is:

S = \frac{b}{m}
