T=5 (n-m)
T=5n-5m
5n=T+5m
n=(T+5m)/5

T=5(n-m)
Expand the brackets.
T=5n-5m
Add 5m to both sides.
T+5m=5n
Divide both sides by 5.
(T+5m)/5=n

The dimensions of a rectangle box are consecutive integers. If the box has volume of 13,800 cubic centimeters, what are its dime
dezoksy [38]

If the dimensions were all the same number ... the box was a cube ...
then each dimension would be  (the cube root of 13,800) cm.

         ∛13,800 = 23.986... (rounded)

so the place to look is around 23 .

(22 x 23 x 24)  =  12,144     <==  too small; go up one integer

(23 x 24 x 25)  =  13,800     <==  Eureka !    

The consecutive integers are  23,  24,  and  25 .

A student is training for the swim team during July and August one summer. She swims one hour every day, while averaging 800 met
Alex787 [66]

Step-by-step explanation:

Please find the attachment.

Let x be the number of hours the student swims per day.

We have been that a student swims one hour every day, so in 2 months the student will swim 60 hours.

We are also told that the student swims 800 meters each day. This means that slope of the graph that represents the total meters swam during the time of her training program will be 800.          

So in 60 days the student will swim 60\times 800=48,000\text{ meters}.

We can see from our attached graph that at x equals 60 our y is approximately 48.

Since y-axis represents the number of meters in thousands, so 48 stands for 48,000.

Therefore, attached graph is the right choice.

Limitation of -4 to the left of the absolute value of x+4 divided by x+4
timama [110]

I believe you're asking about the one-sided limit,

\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4}

Recall the definition of absolute value:

• |x| = x if x\ge0

• |x| = -x if x < 0

Since we're approaching -4 from the left, we're effectively focusing on a domain of x or x+4. So, by the definition above, we have |x+4| = -(x+4). Then in the limit, we have

\displaystyle \lim_{x\to-4^-}\frac{|x+4|}{x+4} = \lim_{x\to-4^-}\frac{-(x+4)}{x+4} = \lim_{x\to-4^-}(-1) = \boxed{-1}
