Let the amount Tom does = x

Then Larissa’s time would be 3x( 3 times the amount of Tom)

And Neal would also be 3x

The total of the 3 is 84 hours so as an equation you have:

X + 3x + 3x = 84

Combine like terms

7x = 84

Divide both sides by 7

X = 84/7

X = 12 hours

Tom = x, so Tom exercised for 12 hours.

What is the value of this expression when n approaches infinity?
topjm [15]

ANSWER

C. 35

EXPLANATION

The given expression is:

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }

As

n \to \:  \infty

\frac{k}{n}  \to0

where k is a constant.

This implies that,

15 - 35 -  \frac{85}{n}  + 55 +  \frac{75}{2n}  +  \frac{15}{2 {n}^{2} }  = 15 - 35 -  0 + 55 +  0+  0 =35

The correct answer is C

Can I get help? And please give the steps to how you got your answer.
lyudmila [28]

Answer:

D

Step-by-step explanation:

First, plot the points they gave you onto a graph (shown in the attached image). The slope is the rise (units up or down from a given point) over the run (units left or right from a given point).

So the slope is 6/4 because to get from the red point to the blue point, you rise 6, and run 4. And from blue to red you rise (remember rise goes up or down) 6 and run 4. 6/4 can be simplified to 3/2 so D is your answer :)
